- Abstract
The effect of vacuum heat treatment on the interface microstructure and tribological property of Cu-coated Ti--6Al--4V alloy is investigated herein. After the vacuum heat treatment process, a diffusion layer is formed at the interface between the Cu coating and the Ti--6Al--4V substrate. The formed intermetallic compounds at the interface between the Ti--6Al--4V substrate and Cu coating are CuTi2, CuTi, Cu4Ti3, and β-Cu4Ti. The activation energy of intermetallic compound growth in the diffusion zone of Cu-coated Ti--6Al--4V is 126.0 kJmol-1, and the pre-exponential factor is 0.1m2 s-1. The tribological properties of the Cucoated Ti--6Al--4V alloy are best when subjected to diffusion treatment at 700 °C for 300 min, with weight loss reduced by 58.2% compared to the Ti--6Al--4V alloy. The wear resistance of the Ti--6Al--4V alloy can be enhanced by Cu coating and vacuum diffusion heat treatment, and the formation of the Cu--Ti intermetallic compound contributes to this improvement. These findings offer new insights for further advancements in the tribological properties of titanium alloys.
