Ceramic material primer powder——DG.NiCrCoAlY, It is resistant to high-temperature oxidation and can reach an operating temperature of 980 degrees Celsius

In the field of thermal spraying, ceramic materials are widely used, especially in high temperature and corrosion-resistant environments. Ceramic materials have become common materials for thermal barrier coatings due to their excellent high temperature resistance and thermal corrosion resistance. They are widely used in the coating preparation of aircraft engines and other workpieces that need to work in high temperature environments. However, due to the large difference in thermal expansion coefficient between ceramic materials and steel substrates, spraying ceramic materials directly on the substrate often results in insufficient adhesion or unsatisfactory bonding effect. Therefore, before spraying ceramic materials, it is very necessary to spray a layer of ceramic material primer.
