摘要 |
<p>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.</p> |
