In order to improve the low wear resistance of Ti-6Al-4V alloy, plasma carburization treatment was newly carried out without consumption of its good specific strength and fatigue life over the temperature. Effect of the plasma carburization was analyzed and compared with the non-treated alloy by microstructural observation, structure characterization and mechanical property test. The plasma treated alloy formed a carburized layer of about 150 μm in depth from the surface, where a fine and hard particles of TiC and V 4 C 3 were homogeneously dispersed through the layer. It was also found that an increase of the wear resistance, fatigue life and hardness, due to the hard and fine dispersoids.
