In situ synthesized high volume fraction WC reinforced Ni-based coating by laser cladding
Source abstract
Abstract
Abstract An in situ synthesized high volume fraction WC reinforced Ni-based composite coating was fabricated on a mild steel substrate by using a high power diode laser. Three kinds of single-layer coatings of different amounts of W+C powder and Ni60 powder and a five-layer coating with different amounts of W+C and Ni60 powders in each layer were prepared. This work showed that the multilayer coating possesses the highest hardness among all coatings, and the maximum hardness of the coatings was about 3.7 times more than that of the substrate. The gradient coating technology combined with the feature that WC particles were liable to sink in the bottom of coating were employed as a new idea for preparing the composite coating free of pores and cracks.
