Effects of Laser Surface Melting on Structure Character and Erosion Resistance of Plasma Sprayed Ceramic Coatings
Published online by Cambridge University Press: 25 February 2011
Abstract
In this work the effects of laser melting on the micro-morphology, structures and solid particle erosion behaviors of plasma spray alumina, alumina-titania and zirconia coatings have been studied. The results have indicated that laser melting has modified the micro-mophologies and structures of coatings, eliminated the porosity of sprayed coatings and increased the erosion resistance of ceramic coatings. The erosion mechanisms of ceramic coatings have been investigated.
