| 摘要 |
<p>The invention relates to a process for obtaining ceramic coatings and ceramic coatings obtained. This process allows obtaining coatings of ceramic oxides, such as ZrO 2 , Al 2 O 3 , TiO 2 , Cr 2 O 3 , Y 2 O 3 , SiO 2 , CaO, MgO, CeO 2 , Sc 2 O 3 , MnO, and/or complex mixtures thereof, by means of a high frequency pulse 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 areas exceeding 60% of the surface of a coating area. The allows producing ceramic coatings with a thickness greater than 30 microns in a single pass.</p> |
