主　　题：plasma clad high-chromium iron-base coating microstructure corrosion resistance 

摘      要：A new type of high-chromium iron-base coating was fabricated on substrate of hardened and tempered grade C steel by plasma cladding with Fe-Cr-C alloy powders. The coating has fine microstructure and is metallurgically bonded to the grade C steel substrate. The corrosion resistance of the coating in solutions of 0. 5 mol/L H2SO4 , 3.5 % NaCl and seawater was evaluated utilizing the electrochemical polarization corrosion-test method. Because of the inherent excellent corrosion- resisting properties of the constituting phase and the fine microstucture, the plasma clad coating exhibits excellent corrosion resistance in the water solutions of 0. 5 mol/L H2S04, 3.5% NaCl and seawater.
