| Abstract: | This paper presents the preparation of a surface with high chromium content forcarbon steel and stainless steel by pack-chromizing in argon gas atmosphere. The depandance ofsurface chromium content, thickness of the chrodrizing layer, sample increment and compositionof coating on chromizing temperature, time and components of pack-chromizing have beeninvestigated A chromium-rich surface coating of 80~94 wt% Cr and 70~82 wt% Cr were obtainedfor the chromizing carbon steel and stainless steel, respectively. The chromized steel with asurface of high chromium content exhibit excellent oxidation resistance below the temperature atwhich surface chromium rediffuses in the steel substrate |
