Title:
MAGNESIUM ALLOY CONNECTION STRUCTURAL MEMBER, ELECTRONIC DEVICE AND MEMBER FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/036254
Kind Code:
A1
Abstract:
The present application relates to the field of terminals. Disclosed are a magnesium alloy connection structural member, an electronic device and a member forming method. The magnesium alloy connection structural member comprises a magnesium alloy body and an electrically conductive layer, wherein a transition layer capable of electrical conduction is formed in an area where the magnesium alloy body is connected to the electrically conductive layer, and the magnesium alloy body is electrically connected to the electrically conductive layer by means of the transition layer. Moreover, the magnesium alloy body is spaced apart from the electrically conductive layer by means of the transition layer, so as to avoid galvanic corrosion generated by the connection between the magnesium alloy body and the electrically conductive layer, thereby prolonging the service life of the magnesium alloy connection structural member, and realizing a stable electrical connection between the magnesium alloy connection structural member and a part such as a main board. In addition, the magnesium alloy body is isolated from the outside by means of the electrically conductive layer, a sealing material and the transition layer, so as to prevent the magnesium alloy body from being oxidized or corroded, and further avoid galvanic corrosion between structures in the magnesium alloy connection structural member.
