Title:
SHEET TITANIUM, A MOULDED ELEMENT PRODUCED THEREFROM AND A METHOD FOR PRODUCING THE SHEET TITANIUM AND THE MOULDED ELEMENT
Document Type and Number:
WIPO Patent Application WO2002058923
Kind Code:
A3
Abstract:
The invention relates to roll-bonded sheet titanium (6), a moulded element produced therefrom (10) and a method for producing the sheet titanium (6) and the moulded element (10). In order to obtain a moulded element (10) which is resistant to high temperatures, sheet titanium (2) is roll-bonded at least on one side with an aluminium film (4), the thickness (d) of said aluminium film being small compared to the thickness (D) of the sheet titanium (2). The aluminium and titanium are converted into an aluminium-titanium alloy, from the adjacent region, by means of heat treatment of the roll-bonded sheet titanium (6). The outer titanium-aluminium alloy layer of the sheet titanium (6) formed in this way is converted into a titanium-aluminium mixture oxide layer by means of contact with oxygen, said layer providing the sheet titanium (6) with good protection against corrosion. Preferably, the moulded element (10) is shaped before the heat treatment for the alloy formation, as the roll-bonded sheet titanium (6) can still be easily deformed.
