Abstract: The Cu-Ce infiltration layer was formed on 304 Stainless Steel surface by double glow plasma surface metallurgy technology. The effects of source voltage and cathode voltage on surface alloying concentration, surface hardness and infiltration layer depth were analyzed by comparative test. The results showed: In the experimental range, the contents of Cu and Ce, surface hardness, deposition layer depth increase with the source voltage increasing, which is contrary to the cathode voltage; the diffusion layer depth increases with either voltage increasing in a certain range.

Abstract: Copper is infiltrated on 0Cr18Ni9 austenitic stainless steel surface by Double Glow Plasma technology, the surface copper content is about 3.5%, content of Cr in metal infiltration layer reaches up to 29.2%. Under the conditions of normal pressure and temperature, corrosion resistance of stainless steel samples which copper infiltrated on surface was researched in 1 mol/L NaOH solution by measurement method of electrochemical. The result shows that, corrosion resistance of copper-infiltrated stainless steel is about 1.67 times higher than untreated sample in 1 mol/L NaOH solution.
