Tribological performance of Ti6Al4V alloy treated by plasma surface Ni alloying

摘要：

　　Plasma surface alloying technology was applied to introduce Ni element into Ti6Al4V to improve its tribological property.The microstructure,composition,phase constituent and hardness of the alloyed layer were examined.Wear mechanisms were discussed on the basis of wear scar observations.The tribological performance of the alloyed layer was investigated by ball-on-disk sliding tests in different environments.The results showed that the Ti-Ni alloyed layer was about 12μm in thickness and the content of Ni element reached to 28% on the surface.The surface hardness of the layer was 677HV,nearly twice as the untreated Ti6Al4V.The wear resistance of the modified Ti6Al4V substrate was improved obviously in different environments.
