| 中文摘要:应用离子渗氮与离子渗硫技术，在钻杆接头材料35CrMo钢表面制备了硫氮复合处理层。采用M-200环块磨损试验机，对比研究了原始渗氮表面与硫氮复合表面在干摩擦条件下的抗磨损性能。结果表明，在干摩擦的条件下，由于摩擦副的接触表面缺乏润滑，硬度较高的渗氮层会加剧接触表面的磨损。而硫氮复合处理层由于在表面存在一层硫化亚铁固体润滑层，在磨损过程中可以起到一定的润滑作用，因此其在干摩擦条件下具备更好的抗磨损性能。 |

| Abstract:Sulphurized-nitrided compound layer is prepared on the surface of drilling pipe joint material 35CrMo steel by the application of ion nitriding and ion sulfurizing technology. Comparative study was made on anti-wear property under dry friction between original nitriding surface and sulphurized-nitrided compound surface. With dry friction, high-hardness nitriding coat would further intensify the wear, because contact surface of friction pair is lack of lubrication; and sulphurized-nitrided compound coat has better anti-wear property, just because there is a layer of solid lubrication coat of ferrous sulfide on the surface. |
