Title:
ANTI-CORROSION TERMINAL MATERIAL, TERMINAL, AND ELECTRICAL WIRE END SECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/138414
Kind Code:
A1
Abstract:
Provided is an anti-corrosion terminal material having a high corrosion-preventing effect and excellent film adhesion. A first film is formed on at least part of a base material, at least the surface thereof comprising copper or a copper alloy. In the first film, a zinc layer comprising zinc or a zinc alloy is formed on a mixed layer with a mixture of a copper/tin alloy region comprising a copper/tin alloy and a tin region comprising tin or a tin alloy other than the copper/tin alloy. The zinc layer is in contact with both the copper/tin alloy region and the tin region of the mixed layer. In a cross section in the thickness direction, the ratio R1/R2 is 0.05-2.5, where R1 (μm) is the length in contact with the copper/tin alloy region, and R2 (μm) is the length in contact with the tin region.
