Plasma-sprayed coatings of corrosion and wear resisting alloys were laser surface melted, with the objective of densifying them and improving their adhesion to the substrate materials. Corrosion resisting coatings of titanium and of 316L stainless steel on steel substrates were remelted with good results. After laser processing, these initially porous coatings were fully dense and exhibited good surface quality. Results with wear resisting coatings were disappointing beause the hard wear resisting phases crack under the tensile stresses developed during cooling. Results are discussed in terms of the effects of the initial coating properties, the laser beam parameters, and other processing variables such as processing atmosphere and sample translation rates.
