作者利用多种表面测试手段对不同条件下的氮离子注入GCr15轴承钢的摩擦学性能进行了研究,发现其表面形貌、表层残余应力、显微硬度、微观组织结构和摩擦磨损性能均与未注入材料的不同。并且指出,由于离子注入引起了表面粗糙度的降低,表层残余应力的增大和表面显微硬度的提高,以及注入层氮化物的形成,所以摩擦磨损机理也发生了变化。试验结果表明,摩擦力和磨损量的降低最高分别可达67％和83％。
The authors investigated the tribological properties of GCr15 bearing steel infiltrated with nitrogen ions under various conditions by using a variety of surface testing methods. The surface morphology, surface residual stress, microhardness, microstructure and friction and wear properties of the GCr15 bearing steel were investigated. Different injection materials. It is also pointed out that the mechanism of friction and wear is also changed due to the decrease of surface roughness, the increase of surface residual stress and the increase of surface microhardness and the formation of nitrides in the implanted layer due to ion implantation. The experimental results show that the friction and wear reduction of up to 67% and 83% respectively.
