| High-temperature coating has a wide application prospect on the area of thermal protection of the turbo-jet, bearing under high temperature, hypersonic aircraft and cutting tools. There are also great potential and good prospects in the technology innovation. The existing research status of high temperature coating is firstly introduced with the main two types of diffusion coating and overlay coating. Then other seven types of ceramic coatings are discussed by different application character. On this basis, it discusses about the preparation technology, the main performance characterization, the high temperature resistant mechanism and the improving perspective of the high temperature coatings. With the development of the relative techniques, the improvement of the high temperature coa-ting performances is not only the resistance of the high temperature, oxidation, creep and erosion, but also the high quality of mechanical and robust performance. |
