"Alumina and stabilized zirconia were plasma sprayed in air using a water-stabilized plasma torch. Nd-YAG laser was then used for additional treatment of the plasma sprayed coatings. The laser was maintained in a quasi-continual regime and defocused from the surface to increase the treated area. Energy density was varied together with the laser scanning velocity to ensure variance in thermal history of the treated surfaces. Microhardness, surface roughness and slurry abrasion resistance (SAR) were measured before and after the laser treatment. Results vary in dependence on the laser treatment parameters. When the laser treatment resulted in substantial changes of the structure (up to a complete re-melting of the surface), enhancement of all measured properties was proven. It is demonstrated that the change of the mechanical properties can be correlated with the optical properties of the coating materials at the laser wavelength."@en . .
