Abstract:
Multicomponent coating development is one of the present research trends in surface engineering applications. Favorable
characteristics of multicomponent laser coatings are advantageous for prolonging tribological service life of wear parts. Low
hardness and poor wear resistance of Ti-6Al-4V surface were enriched by developing laser coatings. In this present work, the
pre-placed powder mixtures of hBN, Graphite, Nickel coated graphite, Nickel-Titanium were laser irradiated to form
multicomponent coatings. The physical characterizations of the coatings were done under SEM, EDS and HR XRD analysis.
Dry-sliding-wear performance was tested and significantly low coefficient of friction (0.15)was noted on the laser coated
samples.
