摘要： An article is provided with improved resistance to hot corrosion through a coating on a metal surface based on an element selected from Fe, Co and Ni, the coating comprising a filled matrix bonded by interdiffusion with the substrate. The matrix is applied by impinging on the substrate metal surface a plurality of heated metallic particles, such as by plasma spraying. The coating includes a filler metal of aluminum and preferably an alloy of aluminum and at least one other element, for example Cr, deposited on and interdiffused with the matrix, such as through a halide vapor deposition process employing a mixture of aluminum powder and other powders. As a result of application of the filler metal, there is provided from the matrix a coating layer of an alloy including an average of about 8 - 20 weight percent aluminum, the application process resulting in substantial recrystallization of the matrix.

摘要： An article having an outer surface and an inner cavity, such as a hole or channel with a metallic inner surface, is provided with an inner metallic coating on the inner surface and, in one form, an outer metallic coating on the outer surface. The inner coating is provided as a result of decomposition and subsequent thermal homogenization of one or more organic compounds including Al, Cr or Ni or alloys including one or more of those elements. The outer coating can be the same as the inner coating or can be a metallic coating of one of a variety of known metallic coatings.
