Abstract
The effects of surface melting produced by a high-power continuous wave CO2 laser on the structure of a 8% yttria partially stabilized zirconia plasma-sprayed coating are reported. The influence of interaction time was studied. Shiny surfaces were produced with an important reduction of superficial porosity at 10.7 kW/cm2 and values of interaction time 12.5 to 25 ms. However a problem of surface unhomogeneity occured.
