Abstract

The surfaces of many engineering components requires the quality of wear and corrosion resistance in order to extend the service life. Laser cladding is one of the surface modification methods to produce high quality, metallurgically bonded coatings on substrates with a minimal heat input into the substrate. Recently, weight reduction and energy consumption of engineering components is required because of resource depletion. One approach for meeting this demand is formation of thin cladding layer on thin substrate. Powder material with small particles are needed in order to form thin cladding layer. The effect of particle diameter on powder melting process is important in laser cladding. In this study, Ni-Cr-Si-B alloy coating was produced in order to investigate the effect of the particle diameter on powder melting process.
