- This paper presents a pulsed laser cladding of TiN-Ti composites used for aero-engine overhaul. In order to analysis the practicability in application, the microstructures, microhardness and other performances of the composite coating were investigated. The results show that the interface between the remanufacturing zone and the substrate is metallurgical bond. The remanufacturing zone is mainly composed of TiN phase and alpha martensite. TiN phases distribute discretely in the remanufacturing coatings and display two typical morphologies, namely the coarse particle TiN and the dendrite TiN. The difference of formation mechanism is the reason why TiN phases display two different morphologies. Compared with the substrate, the repair coatings show better performances on microhardness and wear resistance in same condition. The different performances between remanufacturing coatings and substrate can be mainly attributed to the reinforcement of different TiN phase introduced into the composite coatings. The results above indicate that, it is feasible to repair the aero-engine components by laser cladding of TiN-Ti composites.
