<p>A method of producing a coating on a substrate comprises depositing by electrolytic deposition a metal matrix M1 from a bath containing particles of CrAlM2 so as to co-deposit the particles with the matrix, M1 being Ni or Co or Fe or two or all of these elements and M2 being Y, Si, Ti, Hf, Ta, Nb, Mn, Pt, a rare earth element or two or more of these elements, the deposition being carried out at a current density of less than 3 mA per square centimetre. Preferably, the deposition forms a layer less than 50 νm thick, and occurs at a bath loading of less than 40 g/l of the particles.</p> |
