Abstract
A 1mm thick Al-based composite coating was fabricated on the TC4 Ti-based substrate by using the amorphous powder and the pulse laser cladding technology. The microstructure, phase composition, hardness and friction of the coating were characterized by SEM, DSC, XRD and frictional wear tester, respectively. The results showed that the coating was composed of the micron-sized crystal phases and small amounts of amorphous matrix; the coating has the dense structure and metallurgically bonds with the substrate. The microhardness of the coating was up to 500-600 HV0.2, which was about two times of that of the TC4 Ti-based substrate. The friction coefficient of the coating was lower than that of the TC4 alloy, which improved the friction and wear properties of the TC4 substrate obviously.
