What is alumina ceramic coating?

Alumina ceramic coatings include: alumina coatings, alumina-titania coatings and nano alumina coatings. The powder is refined from micron to nano-scale, and from single component to composite. The coating structure changes from single Layer transition to multi-layer or gradient layer. Beijing It is generally uses plasma sprayed alumina to prepare structural composite coatings and functionally graded coatings, which is one of the hotspots in the research on the microstructure and high temperature oxidation resistance of ceramic coatings at home and abroad.
