A process for the preparation of a metallic coating on a composite body sic / sic

摘要

A metal coating on a part of a ceramic composite is obtained from a powder consisting of a mixture of two powders: & br / - a powder comprising 2 to 5% of a reactive element ti or zr, at least one fusing element b, or if, in proportions which the liquidus between 1000 degree c. and 1300 degrees c. and the metal elements that are complementary, at least 50% ni or ni + co; & br / - a powder b weight ratio of 5 to 30% of which the elements are chosen so as to give the part of the particular properties of the desired surface such as wear anti -, - oxidation and / or anti - corrosion and so as to ensure a liquidus of b is greater than the liquidus of a. & br / a method of construction is also described.
