Method of applying a wear-resistant layer comprising a nickel alloy matrix and intercalated (tungsten carbides and) vanadium carbides to a surface which is to be protected, using the metal spraying route, in particular arc welding or plasma welding, with the aid of a pulverulant filler. The filler essentially comprises: V 3 to 24% by weight or 10 to 60% by weight, Ni 20 to 80% by weight, B 0.1 to 5% by weight, Si 0 to 2% by weight, C 0.1 to 5% by weight, sum (C + B + Si) 0.5 to 12% by weight and sum of all mixture components 100% by weight, and optionally including one or both of W and Cr.
