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.
