Rare earth doped yttrium zirconium oxide spraying material and coating preparation method and application

The invention discloses a rare earth doped yttrium zirconium oxide spraying material and a coating preparation method and application, and belongs to the field of rare earth material preparation. The rare earth doped yttrium zirconium oxide spraying material comprises lanthanum cerium carbonate, yttrium carbonate, aluminum oxide, hydroxyethyl cellulose, dodecyl benzyl ammonium chloride, n-heptane, deionized water, peach gum powder and zirconium oxide. The components in the spraying material are mixed and ball-milled to obtain mixed slurry, then the mixed slurry and peach gum powder are mixed and stirred, and the mixture is subjected to spray granulation and plasma spraying to obtain the rare earth doped yttrium zirconium oxide spraying material coating. Compared with the original yttrium zirconium oxide spraying powder, the lanthanum cerium carbonate and the aluminum oxide are adopted to modify the yttrium zirconium oxide, so that the wear resistance of the spraying powder is improved, the original white coat
