Document Type and Number:
Japanese Patent JP2011246778
Kind Code:
A
Abstract:

To provide a surface treated stainless steel material, capable of forming firmly and uniformly a layer containing Au on stainless steel, while reducing a deposit amount of the Au, and further capable of enhancing conductivity, corrosion resistance and abrasion resistance.

A surface layer 6 containing the Au and Cr is formed on a surface of a stainless steel base material 2, an intermediate layer 2a containing 20 atm.% or more of Cr, and O of 20 atm.% or more and less than 50 atm.% exists at 1 nm or more of thickness between the surface layer and the stainless steel base material, the deposit amount of the Au is 4,000 ng/cm2 or more and less than 70,000 ng/cm2, and a thickness part containing the Cr of 20 atm.% or more is 30% or more with respect to total thickness of the surface layer and the intermediate layer, in this surface treated stainless steel material.
