Abstract
The surface properties of Ti6A14V alloy were investigated by plasma immersion ion implantation (PIII) technique. Modification effect of hot filament gas discharge PIII was compared with that of radio-frequency (RF) glow discharge PHI. The phase composition, and microstructure of samples were characterized by X-ray diffraction (XRD), and Scanning electron microscope (SEM). The microhardness, friction and wear behavior of treated-and untreated-coupons were also measured. The results reveal that the large crystal grains (α-β phase) are changed into small ones. The superhard TiN layer is formed on the surface. The microhardness is increased by 80 percent, friction coefficient is reduced to 0.16, and wear resistance is improved significantly.
