The effect of treating condition on gas nitrosulfidizing of steel was investigated in an atmospher of carrier gas, NH3, and H2S gases mixture in the temperature range of 540°C to 630°C for 30-180min. The weight of terated specimen and the thickness of nitrosulfidized layer increased exponentially with the treating temperature. The hardness of surface slightly decreased with increasing treating temperature and that of compound layer reached the maximum value at 570°C. X-ray diffraction indicated that the surface products were FeS, Fe1-xS, Fe3N, Fe4N, etc. at each treating temperature.
