摘　　要：为了提高钻杆接头的使用寿命,利用离子渗氮和硫氮共渗技术在钻杆接头材料35CrMo钢表面制备了氮化层和硫氮共渗层。在油润滑条件下采用自制的球-盘磨损试验机考察了表面渗层的摩擦磨损性能。利用了XRD研究了表面层的相结构,采用了带EDS的SEM对表面改性层和磨损表面进行了分析。结果表明:35CrMo钢硫氮共渗层的摩擦学性能明显优于原始渗氮层;具有优良润滑作用的FeS固体润滑膜在高硬度氮化层的支撑下,可以有效地改善钻杆接头的摩擦磨损性能。In order to improve the using life of drilling joints, nitrade layer and sulfur-nitrade layer were produced on the 35CrMo steel surface by ion nitriding technology and ion nitriding-sulfuring technology. A ball-on-disc wear tester was used to investigate the tribological properties of the nitrided and nitrided-sulphurized surfaces under oil lubrication. XRD was used to analyze the phase of the layers, and SEM with EDS was used to analyze the surface modification layer and the worn surface. The results show that the tribological properties of the surface treated by nitriding and surphuration is better than the one treated by nitriding. With the support of harden nitrade layer, the sulphide layer could improve the wear resistant behaviors of the drilling joint material effectively.
