THE EFFECT OF SUBSTRATE ROUGHNESS ON THE MORPHOLOGY AND ADHESIVE STRENGTH OF YSZ COATINGS DEPOSITED WITH A FORE VACUUM PLASMA-CATHODE ELECTRON SOURCE
We present the experimental results on electron-beam deposition of Y<sub>2</sub>O<sub>3</sub>-stabilized zirconium dioxide ceramic coatings using a fore vacuum plasma-cathode electron source. The influence of the substrate roughness on the structure and roughness of the coating was evaluated. It was found that, at the roughness of the substrate Ra 1.96-0.21 microns, the coatings have the best adhesive properties. Coatings are subject to destruction due to inelastic deformation and mechanical coupling with the substrate.
