| Abstract: |
| An aluminized layer is formed on the surface of Ti6Al4V substrate by using the double glow discharge plasma surface modification process, the phase structure and micro-hardness of the layer are analyzed, also the friction and tribological behavior of the layer is investigated by a ball on disk sliding wear machine. The results indicate that the aluminized layer is composed by TiAl3 and Al and the micro-hardness of samples increases significantly; besides the wear test results show that the coefficient of friction and the wear volume decreases after aluminizing. From the wear scar we know that the wear mechanism is adhesion wear. Thus it is feasible to improve the friction and wear properties by glow discharge plasma surface modification. |
