Abstract
There is provided a metal plate coated stainless material (100) which includes a stainless steel sheet (10) having formed thereon a passivation film (11) having a Cr/O value in the range of 0.05 to 0.2 and a Cr/Fe value in the range of 0.5 to 0.8 at the surface as measured by an Auger electron spectroscopy analysis and a metal plated layer (20) formed on the passivation film (11) of the stainless steel sheet (10), in which the metal plated layer (20) is a plated layer formed from any one metal selected from among Ag, Pd, Pt, Rh, Ru, Cu, Sn and Cr, or an alloy of these metals.
Claims7
A metal plate coated stainless material comprising:
- a stainless steel sheet coated with a metal plated layer which is deposited on a passivation film present on the surface of the stainless steel sheet, wherein
- the passivation film has a surface composition having a Cr/O value comprised within a range from 0.05 to 0.2 and a Cr/Fe value comprised within a range from 0.5 to 0.8, the Cr/0 value and the Cr/Fe value obtained by Auger electron spectroscopy analysis, and
- the metal plated layer is formed from any one metal selected from among Ag, Pd, Pt, Rh, Ru, Cu, Sn and Cr, or an alloy composed of at least two or more metals selected from among these metals.
