涂层材料的磨损研究

Research on Wear of Coating Materials

研究了化学复合镀Ｎｉ－Ｐ－ＳｉＣ，Ｎｉ－Ｐ－Ａｌ_２Ｏ_３，Ｎｉ－Ｐ－ＰＴＦＥ三种复合涂层的摩擦磨损特性。研究了载荷对复合涂层耐磨性的影响;比较了三种涂层的抗咬合性能。结果发现低载荷下，减摩涂层具有更好的耐磨性；高载荷下抗磨涂层具有更好的耐磨性。

In this paper the wear characteristic of electroless composite coatings Ni-P-PTFE,Ni-P-SiC and Ni-P- Al_2O_3 were studied. The effect of load on the wear resistance of composite coatings was studied and the anti-seizing of three composite coatings was compared.The results show that the Ni P-PTFE coating has good wear resistance at low load and the Ni-P-SiC and Ni-P- Al_2O_3 coatings have good wear resistance at high load.
