Abstract
An arc hardfacing rod including a tubular member, a filler material, an insulating coating and a plurality of discrete metal carbide particles set within the insulating coating such that a surface of a portion of the metal carbide particles is uncovered. The filler carbide particles include tungsten carbide particles, titanium carbide particles, tantalum carbide particles, niobium carbide particles, zirconium carbide particles, vanadium carbide particles, hafnium carbide particles, molybdenum carbide particles, chromium carbide particles, silicon carbide particles and boron carbide particles, cemented composites and mixtures thereof. Adhered to the exterior surface of the tubular member is an insulating coating including a coating flux and a coating bonding agent. A plurality of discrete metal carbide particles are set within the insulating coating such that a surface of a portion of the metal carbide particles is uncovered. The metal carbide particles may be of the same composition as the filler carbide particles forming the filler material or the metal carbide particles may be macrocrystalline tungsten carbide particles, cast tungsten carbide particles, crushed sintered cemented tungsten carbide particles or pelletized cemented tungsten carbide particles, and mixtures thereof.
