Abstract

Thermodynamic calculations were made to find an optimum condition of simultaneous chromizing and aluminizing of mild steel. Results of calculations showed that Cr-Al alloy powder should be used and the optimum composition was 90~95wt% Cr and 5~10wt% Al. Simultaneous chromizing and aluminizing of a mild steel was achieved using 95Cr-5Al wt% alloy powders as a masteralloy, NH4Cl as an activator at $1273^{\circ}$K under Ar atmosphere.
