  • Publication number: 20190376202
    Abstract: An enhanced anodization method includes forming a porous anodization layer comprising columns of anodization layer material with pores between adjacent columns. The method further includes sealing the porous layer by forming a sealing layer at a top of the porous layer. The sealing layer may be formed by using a hybrid sealing process that combines, in any order, two or more of de-ionized (DI) water seal, Ni sealing, and, PTFE sealing. Alternatively, the sealing layer is formed by conformally coating the columns in the porous layer with one or more layers of a coating material. Further, the coating material may be surface-fluorinated to improve plasma resistance.

  • Publication number: 20180251406
    Abstract: Disclosed herein are methods for fabricating layered ceramic materials via hot pressing. A method includes disposing a powder compact or a ceramic slurry onto a surface of an article, wherein the article is a chamber component of a processing chamber. The powder compact or ceramic slurry is hot pressed against the surface of the article by heating the article and the powder compact or ceramic slurry and applying a pressure of 15-100 Megapascals. The hot pressing sinters the powder compact or ceramic slurry into a sintered ceramic protective layer and bonds the sintered ceramic protective layer to the surface of the article.
