| Abstract: | In this work the effects of laser melting on the microstruture and the solid particle erosion behavior of flame sprayed Ni-Cr-B-Si and Fe-Cr-B- alloy coatings, plasma sprayed chromium carbide (Ni-Cr) and WC-Co (Ni-Cr) alloy coatings have been studied. The results have shown that laser melting has modified the microstructure of sprayed coatings, eliminated the porosity of sprayed coatings and increased the erosion resistance of the coatings, The erosion mechanisms of these coatings have been investigated. |
