The CoTi3SiC2/Cu composite coatings fabricated by laser cladding exhibit excellent tribological and anti-wear performances in extreme environments, with significantly increased hardness and a transition from severe plastic deformation wear to slight oxidative adhesive wear.
For the needs of the key moving parts of SUS304 steel in extreme environments, the composite coatings (CoTi3SiC2/Cu) were successfully fabricated by laser cladding. The tribological behaviors of three coatings at room temperature and 600 degrees C were systematically studied. Results indicated that the microhardness of the three coatings was 1.2-1.8 times higher than the SUS304 substrate. With the addition of the Ti3SiC2 and Cu, the coating had good tribological capabilities, especially the anti-wear at room temperature was increased by 96%, and the friction reduction at 600 degrees C was increased by 73%, even it was found that Cu could promote the lubrication of Ti3SiC2. The wear of the three coatings changed from severe plastic deformation to slight oxidative adhesive wear.
