摘要：
The NiCr/Cr3C2-10CaF(2) (wt-%) composite coatings were fabricated on Ti-6Al-4V alloy by laser surface alloying. Ageing treatments were performed at 600 degrees C for 0, 24, 48 and 96 h, respectively. Microstructure and tribological properties of the as-laser-alloyed and aged composite coatings were investigated systematically. Results showed that microstructure became more homogeneous after ageing at 600 degrees C for 48 h. Wear rates and friction coefficients of the aged composite coatings were slightly higher than that of the as-laser-alloyed coating. It indicates that microstructure and tribological properties of the composite coatings present good high-temperature stability.
