    摘要: A method of creating a plasma-resistant thermal oxide coating on a surface of an article, where the article is comprised of a metal or metal alloy which is typically selected from the group consisting of yttrium, neodymium, samarium, terbium, dysprosium, erbium, ytterbium, scandium, hafnium, niobium or combinations thereof. The oxide coating is formed using a time-temperature profile which includes an initial rapid heating rage, followed by a gradual decrease in heating rate, to produce an oxide coating structure which is columnar in nature. The grain size of the crystals which make up the oxide coating is larger at the surface of the oxide coating than at the interface between the oxide coating and the metal or metal alloy substrate, and the oxide coating is in compression at the interface between the oxide coating and the metal or metal alloy substrate.

    摘要: An article which is resistant to corrosion or erosion by chemically active plasmas and a method of making the article are described. The article is comprised of a metal or metal alloy substrate having on its surface a coating which is an oxide of the metal or metal alloy. The structure of the oxide coating is columnar in nature. The grain size of the crystals which make up the oxide is larger at the surface of the oxide coating than at the interface between the oxide coating and the metal or metal alloy substrate, and wherein the oxide coating is in compression at the interface between the oxide coating and the metal or metal alloy substrate. Typically the metal is selected from the group consisting of yttrium, neodymium, samarium, terbium, dysprosium, erbium, ytterbium, scandium, hafnium, niobium or combinations thereof.

    摘要: Particulate generation has been a problem in semiconductor device processing in highly corrosive plasma environments. The problem is exacerbated when the plasma is a reducing plasma. Empirically produced data has shown that the formation of a plasma spray coated yttrium-comprising ceramic such as yttrium oxide, Y2O3—ZrO2 solid solution, YAG, and YF3 provides a low porosity coating with smooth and compacted surfaces when such ceramics are spray coated from a powder feed having an average effective diameter ranging from about 22 μm to about 0.1 μm. These spray-coated materials reduce the generation of particulates in corrosive reducing plasma environments.
