A method of fabricating an aircraft part comprising a substrate and a coating layer on the substrate.

摘要

1/1 summary "method for fabricating an aircraft part comprising a substrate and a substrate coating layer" a method for fabricating a part (1) comprising a metal (sub) substrate at least partially covered in a coating layer ( see), the process comprising: • preparing (a) a surface of the substrate (sub) to cover to obtain a prepared surface of roughness ra falling in the range of 0.6 µm to 1.6 µm, and preferably in the range of 0.8 µm to 1.6 µm; • forming (c) the coating layer (rev) on the prepared surface of the substrate, this coating layer (rev) being formed by spraying, using an hvof-type spraying method to pulverize a carbide grain (g) powder-containing powder mixture metal, the grains (g) having dimensions that are strictly smaller than 1 µm and the thickness (epmin) of the coating layer (rev) as formed in this way being less than 50 µm; then finishing at least one surface of said coating layer (rev) by polishing (d) in such a manner as to ensure that its roughness ra is less than 1.6 µm.
