DETAILED DESCRIPTION

Definitions [0010] For convenience, before further description of the present disclosure, certain terms employed in the specification, and examples are described here. These definitions should be read in the light of the remainder of the present disclosure. The terms used herein have the meanings recognized and known to those of skilled in the art, however, for convenience and completeness, particular terms and their meanings are set forth below.

[001 1 ] The articles“a”,“an”, and“the” are used to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article.

[0012] The term“about” when referring to a numerical value is intended to encompass the values resulting from variations that can occur during the normal course of performing a method. Such variations are usually within plus or minus 5 to 10 percent of the stated numerical value.

[0013] The term liquid metal” refers to the class of amorphous alloys that are obtained by slow cooling rates.

[0014] The term“alloy” refers to the class material that may be referred to as a solid solution of metals. The alloy in the present disclosure refers to a magnesium alloy selected from AZ91 D, AZ31 B, LZ91 , ALZ991 , AI6083, AI80 or combinations thereof.

[0015] The term“molded”, and variations, such as“molding”, used herein refer to injection molding of alloy on a surface of liquid metal substrate.

[0018] The term“substrate”, used herein refers to the frame containing liquid metal that is usable to obtain the enclosure of the present disclosure. The substrate is noted to be compatible for die-cast or tbixomolding techniques and structurally may be molded as per end use.

[0017] The term“injection molding”, used herein refers to the technique for manufacturing parts by injecting molten material into a mold. Herein, the term refers to injection molding of metal alloys onto a surface of liquid metal substrate. Injection molding may be carried out by a process, such as thixo-molding or die casting.

[0018] The term “mechanically stable”, used herein refers to substrates having high tensile strength and/or high resistance to breakage and/or high corrosion resistance. [0019] The term “high gloss edges”, used herein refers to chamfered surfaces (in particular the edges) of the substrate that reveal shiny edges.

[0020] Encasement or body of electronic devices are made of metal enclosures that require both strength and aesthetic appeal. Metal alloys, such as magnesium alloy substrates are prone to corrosion and, also suffer from poor tensile strength. However, their low density and compatibility with associated techniques, such as spray coating and/or electrophoretic deposition makes such alloys attractive choices for enhancing aesthetic appeal of substrates.

[0021] Enhancement of aesthetics is in particular desirable, for electronic encasement; and every endeavor in this regard is considered worthwhile. High gloss finish is particularly considered desirable, however the employment of metal substrates, such as magnesium alloys is noted to yield poorer finish. A lustrous over-coat is noted to be necessary for ensuring acceptable finish.

[0022] However, ensuring uniform glossy finish over the body of an electronic device may be challenging. The aesthetically pleasing rounded edges of laptops, tablets, mobile phones and the like, are noted to possess relatively inferior gloss finish, owing to surface corrosion occurring on CNC diamond cut chamfered areas of magnesium alloy materials. Liquid metal material can have much better durability against corrosion resistance and may be mechanically stable.

[0023] The present subject matter describes examples of injection molding an alloy on a surface of liquid metal substrate, the injection molded alloy additionally results in high tensile strength and thus, enhanced durability. In an example, the tensile strength of the alloy injection molded liquid metal substrate may be in a range of, from about 800 to about 1200 MPa as measured by American Society for Testing and Materials (ASTM) D790. This is found to be a clear enhancement from the primary component, i.e., the magnesium alloy having a tensile strength from about 40 to about 700 MPa. The alloy may be a magnesium alloy selected from AZ91 D, AZ31 B, LZ91 , ALZ991 , AI6063, AI80 or combinations thereof. The injection molding may be carried out by thixo-moiding or die-casting at a temperature from about 800 °C to about 1850 °C. The liquid metal substrate may be pre-fabricafed into a suitable format or mold and the injection molding is carried out on the said mold. The molded alloy may have a thickness of, from about 0.3 mm to about 2.0 mm. The alloy having a thickness beyond 2.0 mm leads to substrates that are unsuitable for forming enclosures of electronic devices owing to excess weight. On the other hand, an alloy having a thickness lower than 0.3 mm is too weak and mechanically unstable

[0024] Further, the molded alloy is readily adaptable to techniques, such as electrophoretic deposition or spray coating, thus allowing relatively easy deposition of a decorative layer that can provide enhancement of aesthetic appeal of the thus obtained enclosure. The decorative layer may have a thickness from about 8.0 pm to about 65.0 pm. Said enclosure is particularly suitable for electronic devices.

[0025] Further, chamfering of the alloy injection molded substrate, with or without decorative layer, may provide high gloss finish at the edges. Chamfering may be carried out by a CNC diamond cutting machine or a laser engraving machine. In an example, the chamfering may be carried out with a laser engraving machine having a Nd:YAG laser under a laser power from about 20 to about 200 W and an engraving speed from about 100 to about 300 mm/minute. In another example, the laser etching may be carried out under a laser power in a range from about 50 to about 150 W and an engraving speed from about 120 to about 280 mm/minute. In another example, the laser etching may be carried out at a laser power of about 100 W and an engraving speed of about 200 mm/minute. In another example, the chamfering may be carried out with a CNC diamond cutting machine at speed from about 6000 to about 25000 rpm. Chamfering results in an etching that reveals the underlying shiny liquid metal surface.

[0026] The aesthetic quality of thus obtained enclosures may be quantified by measuring a gloss value. In an example, the gloss value of the chamfered enclosure may be in a range from about 85 to about 97 units as measured by American Society for Testing and Materials (ASTM) D523 at a viewing angle of about 60°. This is found to be a clear enhancement from the unchamfered enclosures that result in a gloss value in the range from about 60 to about 75 units as measured by American Society for Testing and Materials (ASTM) D523 at a viewing angle of about 60°. In another example, the gloss value of the chamfered surface decoration layer may be in a range from about 87 to about 95 units as measured by ASTM D523 at a viewing angle of about 60°. Overall, the methodology of molding an alloy and the further deposition of a decorative layer on the alloy injection molded liquid metal substrate, according to the present subject matter, is simple and easy, and the enclosures thus obtained are aesthetically appealing, while also being mechanically stable.

[0027] The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several examples are described in the description, modifications, adaptations, and other implementations are possible. Accordingly, the following detailed description does not limit the disciosed examples instead, the proper scope of the disclosed examples may be defined by the appended claims.

[0028] Fig. 1 illustrates a sectional view of an alloy injection molded liquid metal substrate 100, according to an example of the present disclosure. The alloy injection molded liquid metal substrate 100 includes a liquid metal substrate 102 and an alloy 104. The liquid metal substrate 102 may be made of titanium, aluminium, chromium, zirconium, tin, or combinations thereof in an example, the liquid substrate 102 can be a combination of titanium and zirconium

[0029] in an example, the liquid metal substrate 102 may be of a thickness in a range from about 0.3 to 2.0 mm. In an example, the liquid metal substrate 102 may be of a thickness in a range from about 0.5 to 1.8 mm. in another example, the liquid metal substrate 102 may be of a thickness of 1.1 mm.

[0030] in an example, the liquid metal substrate 102 may be made from an injection molding process.

[0031] As described above, the ailoy injection molded liquid metai substrate 100 includes the ailoy 104 injection molded on a first surface of the liquid metai substrate 102. The alloy may be molded on the first surface of the liquid metai substrate, such that a portion or the whole of the surface may be in contact with the alloy. The alloy may be a magnesium alloy selected from AZ91 D, AZ31 B, LZ91 , ALZ991 , AI8083, AI80 or combinations thereof. In an example, the ailoy 104 can be AZ31 B. in another example, the ailoy 104 may be made of AZ91 D. [0032] The presence of liquid metal substrate 102 in the alloy injection molded liquid metal substrate 100 renders it mechanically stable. In an example, the alloy injection molded liquid metal substrate 100 may provide an enhanced tensile strength in a range from about 800 to about 1200 MPa. In another example, the alloy injection molded liquid metal substrate 100 may provide a tensile strength In a range from about 900 to about 1 100 MPa. in another example, the alloy injection molded liquid metal substrate 100 may provide a tensile strength of about 1000 MPa.

[0034] The decorative layer 202 may be deposited on a portion or the whole surface of the alloy injection molded liquid metal substrate. Also, the decorative layer may be deposited onto more than one surface of the alloy injection molded liquid metal substrate in an example, the decorative layer 202 may be deposited onto two surfaces of the alloy injection molded liquid metal substrate. In another example, the decorative layer 202 may be deposited wholly on the first surface and on a portion of the second surface of the alloy injection molded liquid metal substrate. In case of decorative layer being deposited on a portion of the surface, the decorative layer may be deposited onto at least 10% of the surface of the alloy injection molded liquid metal substrate in an example, the decorative layer may be deposited onto at least 20% of the surface of the alloy injection molded liquid metal substrate. In an example, the decorative layer may be deposited onto at least 45% of the surface of the alloy injection molded liquid metal substrate in an example, the decorative layer may be deposited onto at least 65% of the surface of the alloy injection molded liquid metal substrate.

[0035] Fig. 3 illustrates an electronic device with a sectional view 300 of an alloy injection molded liquid metal substrate (comprising the alloy 104 that is injection molded on the liquid metal substrate 102) with chamfered edges 302, according to an example of the present disclosure. In an example, chamfering the alloy injection molded liquid metal substrate, may lead to enhanced gloss value from about 85 to about 97 units as measured by American Society for Testing and Materials (ASTM) D523 at a viewing angle of about 60°. in an example, the chamfering may lead to a gloss value from about 87 to about 95 units in another example, the chamfering may lead to a gloss value of about 90 units.

Injection molding 402 may be carried out at a temperature from about 800 °C to about 1650 °C in an example, the injection molding may be carried out at a temperature from about 850 °C to about 1600 °C. In another example, the injection molding may be carried out at a temperature from about 900 °C to about 1550 °C. in another example, the injection molding may be carried out at a temperature from about 1000 °C to about 1400 °C.

[0038] As shown in the Fig. 4, an a!ioy 104 can be molded onto a first surface of a liquid metal substrate 102. in an example, the alloy 104 may be thixomo!ded on the liquid metal substrate 102. In another example, the alloy 104 may be die- casted on the liquid metal substrate 102.

[0039] The alloy 104 may be molded on a portion or the whole surface of the liquid metal substrate. Also, the alloy may be molded onto more than one surface of the liquid metal substrate 102. In an example, the alloy 104 may be molded onto two surfaces of the liquid metal substrate 102. In another example, the alloy 104 may be molded wholly on the first surface and on a portion of the second surface of the liquid metal substrate 102. In case of the alloy being molded on a portion of the surface, the alloy may be injection molded onto at least 10% of a surface of the liquid metal substrate 102 In an example, alloy may be injection molded onto at least 20% of the liquid metal substrate 102. in an example, alloy may be injection molded onto at least 45% of the liquid metal substrate 102. In an example, alloy may be injection molded onto at least 85% of the liquid metal substrate 102.

[0040] in an example, the injection molding 402 may be carried out by combining the alloy selected from AZ91 D, AZ31 B, LZ91 , ALZ991 , AI6083, AI80 or combinations thereof. The mixture may be poured into the liquid metal mold at an elevated temperature from about 800 °C to about 1650 °C. The molten alloy in the mold may be allowed to cool and solidify. The solidified materia! may be cleaned, washed, polished, degreased, and activated. The cleaning and washing may be performed using a buffer solution, which may help in removing foreign particles, if any, present on the surface of the solidified material. Further, the solidified material may be chemically polished using abrasives to remove irregularities that may be present on the surface of the solidified material. The solidified material may also be degreased through ultrasonic degreasing methods to remove impurities, such as fat, grease, or oil from the surface of the solidified material.

[0050] The decorative layer 202 may comprise top coat, in combination with one or more other layers. The top coat may also be applied as single or multiple coats to achieve desired thickness and finish. In an example, the top coat may have a thickness from about 10.0 pm to about 25.0 pm. In another example, the top coat may have a thickness from about 12.0 pm to about 22.0 pm. In another example, the top coat may have a thickness of about 17.0 pm. In an example, the top coat may be made of poiyacry!ic acid, polyurethane, urethane acrylates, acrylic acrylates, epoxy acrylates, or combinations thereof. In an example, the top coat is made of polyacry!ic acid. In another example, the top coat may be made of polyurethane. In another example, the top coat may be made of urethane acrylates.

[0051 ] in an example, the top coat deposited by spray coating may be followed by UV treatment in a range from about 700 mJ/cm ² to about 1200 mJ/cm ² for a period in a range from about 10 seconds to about 30 seconds.

[0052] The alloy surface 104 may be cleaned, degreased, washed and passivated prior to deposition of the decorative layer. Fig. 7 illustrates a method of fabrication of an enclosure 700 comprising passivation. The alloy injection molded liquid metal substrate may be passivated 702, prior to electrophoretic deposition 504. Passivating the magnesium alloy 702 may be carried out by treating alloy injection molded liquid metal substrate with a salt of molybdate, vanadate, phosphate, chromate, stannate, manganese, or combinations thereof in an example, passivation may be carried out by using a salt of molybdate.
