Abstract: Compared with the single sulphurating treatment,the duplex treatment of nitrocarburizing-sulphurating can more effectively improve the properties of steel such as friction-reducing,wear resistance and anti-scuffing.Under the same processing parameters,the sulphide layers were fabricated on the surface of CrMoCu alloy cast iron by single ion-sulphurating treatment and nitrocarburizing-sulphurating duplex treatment,respectively.Through the analysis of the sulphide,the effect of the nitrocarburizing on the fabrication of the sulphide layer was investigated.And the result shows that the fabrication of sulphide layer is promoted by the nitrocarburizing treatment.
