| 简介 |
The method involves introducing a material e.g. ceramic, which is in the form of powder, in plasma jets of plasma torches (10, 20), respectively, where the ceramic is chosen among e.g. yttrium zirconia, and zirconia stabilized with calcium oxide, magnesium oxide, cerium oxide and rare earth oxides. The torches are arranged in an enclosure (2) and are oriented such that the jets cross to create a plasma jet which is directional. A substrate (40) is placed in an axis of the directional plasma jet such that the substrate is affected by the material in vapor phase. Independent claims are also included for the following : (1) an installation for depositing a thermal barrier on a substrate (2) a thermomechanical part obtained from a thermal barrier depositing method. |
