【Abstract】 Studies of anodic polarization in 0.5mol/l H2SO4 were made to examine the corrosion behaviour and microhardness of surface alloys formed by implanting N,B,Cr and Mo ions into pure iron specimens. No notable change of corrosion potential was observed.The critical and passive current densities, however, were decreased markedly. It was:found that the range of passivity was increased and the microhardness improved. Results;suggested, also, that multi-element ion implantation was better than single-element ion. implantation.更多还原
