摘要
采用Ｘ射线法测量了Ｎｉ－Ｐ－Ｓｉ３Ｎ４复合镀层经热处理后在镀层中产生的残余应力，并与Ｎｉ－Ｐ镀层进行了对比研究。同时，着重分析了镀层残余应力和磨损性能的关系。结果表明，Ｎｉ－Ｐ－Ｓｉ３Ｎ４复合镀层中Ｐ含量较低时为压应力，镀层磨损量较低；Ｐ含量较高时为拉应力，镀层脆性脱落严重，磨损量增大。对于ＮｉＰ镀层，随着镀层中Ｐ含量的增大，拉应力逐渐增大，磨损加剧；而Ｐ含量较低时，表现为粘着磨损。
In this paper,the remanent stress in Ni-P-Si3N4 composite plating after heat treatment is measured by the method of X-ray diffraction.The comparative research is also done with Ni-P-plating. In the mean time,the relation between remanent stress in plating and wear performance is emphatically analysed.The results indicate that when P content in Ni-P-Si3N4composite plating is lower,it is in the state of compression stress and lower wearing volume.when P content is high,it is in the state of tension stress and serious brittle dropping appears, the wearing volume also rises.As for Ni-P-plating,tension stress rises with the increasing of P content in plating and wear is serious.When P content is low,adhesion wear appears.
