METHOD FOR OBTAINING CERAMIC COATINGS AND CERAMIC COATINGS OBTAINED

摘要

This method makes it possible to obtain coatings of ceramic oxides, such as ZrO₂, Al₂O₃, TiO₂, Cr₂O₃, Y₂O₃, SiO₂, CaO, MgO, CeO₂, Sc₂O₃, MnO, and/or complex blends thereof, by means of a high-frequency pulsed-detonation technique in which the relative movement between the combustion stream and the substrate or piece to be coated takes place at a speed that produces an overlap between the successive coating zones in excess of 60% of the surface of a coating zone. The method makes it possible to produce ceramic coatings with a thickness greater than 30 microns in a single pass.
