Patent ID: 10113238

Abstract:
There is provided a gold plate coated stainless material characterized by comprising: a stainless steel sheet formed with a passivation film having a surface of which a Cr/O value is within a range of 0.05 to 0.2 and a Cr/Fe value is within a range of 0.5 to 0.8 when measured by Auger electron spectroscopy analysis; and a gold plated layer formed on the passivation film of the stainless steel sheet. According to the present invention, there can be provided a gold plate coated stainless material which can be improved in the coverage and interfacial adhesion property of the gold plated layer formed on the stainless steel sheet even when reducing the thickness of the gold plated layer, thereby to be excellent in corrosion resistance and conductivity and advantageous in cost.
