Estimating the term…
A multi-component sealing coating powder material and a preparation method thereof are provided, which relates to the technical field of thermal spraying materials. The multi-component sealing coating powder material includes the following raw materials in parts by weight: 10-20 parts of titanium aluminide powder, 2-8 parts of muscovite powder, 5 -15 parts of boron nitride powder, 65-75 parts of Al-based mixed powder, and 0.1-5 parts of a binder. The Al-based mixed powder is at least one of aluminum powder, alumina spheres, and alumina grinding powder. The multi-component sealing coating powder material exhibits good adaptability to the plasma spraying process and yields coatings with high quality and stability. It effectively solves problems of traditional aluminum-based suspension coatings in poor coating structural uniformity, low bond strength, and poor abradability caused by significant compositional fluctuations and insufficient processing stability.
An application of a multi-component sealing coating powder material in plasma spraying for preparing a sealing coating, wherein the multi-component sealing coating powder material comprises the following raw materials in parts by weight:
12-15. parts of titanium aluminide powder, 4-6 parts of muscovite powder, 8-11 parts of boron nitride powder, 70-73 parts of aluminum (Al)-based mixed powder, and 0.1-2 parts of a binder;
