Surface morphology, microstructure and wear morphology of the coatings were investigated using model KYKY-2800 scanning electron microscope modeled. Phases of the coatings were analyzed using model D/max-RA X-ray diffractometer. Microhardness of the coatings was tested using model MH-6 hardness-testing device. The wear-resisting property of coatings was compared with 65Mn steel treated by the quenching and backfiring technology using the home-made abrasion machine. The feasibility was analyzed for reactive electric-spark build-up welding TiN cermet coating to be used for gear shaft restoration.
