Abstract: The invention relates to a material for coating a surface by means of at least partial thermal phase change, comprising a first component with several metal ingredients to form a matrix, ans a second component to form a hard phase embedded in the matrix, wherein the first component, based on the total weight thereof, has a fraction of at least about 40% nickel and the second component is a fraction based on the total weight of the material between about 20% and about 80% and the first component, based on the total weight thereof, has a fraction of at least about 10%, in particular, at least about 20% of a further metal from the group of copper or iron.

Abstract: Method for applying a wear-resistant layer comprising a nickel alloy matrix and intercalated tungsten carbides and/or vanadium carbides to a surface which is to be protected using arc welding or plasma welding.

Abstract: A consumable nickel-tungsten-carbon electrode is used in arc welding deposition of a corrosion resistant layer producing a nickel-alloy matrix containing tungsten carbide inclusions on a surface of a metal workpiece by electric arc deposition under parameters such that there is either practically no solubilization of the tungsten carbide grains in the filling of the nickel tube of the electrode or there is substantially complete solubilization of the tungsten carbide grains and reprecipitation of the tungsten carbide inclusions in the matrix on cooling.
