Abstract

The characteristics of the chromized layer of steel 45 after low temperature salt-bath chromizing with different pre-heat treatments were investigated using OM,SEM,XRD.A chromized layer with good properties could be obtained in steel 45 with the ion-nitriding pre-heat treatment,and the chromized layer was composed of the phases Cr23C6,CrN,Cr/Fe,(Cr,Fe)7C3 and (Cr,Fe)2N.
