| Abstract: | To improve the wear resistance of titanium alloy,niobium gradient modified layer was prepared on surface of Ti6Al4V(TC4) by plasma surface alloying process firstly,then carburizing was conducted to form the Nb-C composite gradient modified layer.Micro-structure,ingredient distribution,phase structure and hardness distribution of the modified layer were analyzed.Pin-on-disc test was also carried out,and the results indicated that Nb and C elements were distributed by a gradient,the modified layer was mainly composed of Ti,TiC,Nb2C,NbC phases etc.Surface hardness of the modified layer Ti-Nb-C was up to 800 HK.Wear resistance was improved obviously after Nb-C surface composite treatment. |
