A method of producing a coating on a substrate comprising aluminising, chromising or siliconising the substrate and depositing on the treated substrate by electrolytic or electroless deposition a metal matrix M1 from a bath containing particles of CrAlM2 so as to co-deposit the particles with t he 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. Preferably, the method includes platinum aluminising of the substrate. Heat treatments may be incorporated before and after code deposition of the M1CrAlM2.
