Abstract

Official abstract text for this publication.

Provided is a plating film containing Au and Tl, including Tl oxides including Tl2O on a surface of the plating film, a ratio of Tl atoms constituting Tl2O to a total of Tl atoms constituting the Tl oxides and Tl atoms constituting Tl simple substances on the surface being 40% or more.

First claim

Opening claim text (preview).

The invention claimed is: 1. A plating film containing Au and Tl, comprising: Tl oxides including Tl 2 O on a surface of the plating film, a ratio of Tl atoms constituting Tl 2 O to a total of Tl atoms constituting the Tl oxides and Tl atoms constituting zero valent Tl on the surface being 40% or more. 2. The plating film according to claim 1 , wherein a content of Tl contained in the entire plating film is 10 ppm or more and 600 ppm or less in mass ratio. 3. The plating film according to claim 1 , wherein the plating film has an average thickness of 0.1 μm or more. 4. A plated member comprising a base material and a plating film coating the base material, and to be joined to a mating member via an electrically conductive joining material, the plating film being the plating film according to claim 1 . 5. The plated member according to claim 4 , wherein the base material includes a plate material, and a film composed mainly of Ni coating the plate material, and the plate material is made of a metal including one type or more selected from Cu, Ag, Al, Mo, W, and Mg, or a composite material including one type or more selected from Cu, Ag, Al, Mo, W, and Mg and one type or more selected from diamond and silicon carbide.
