Abstract

A brazing rod is disclosed for use in depositing an abrasive metal coating on a metal substrate. The brazing rod comprises an elongate metal tube made of a metal selected from the group consisting of copper, bronze, brass, nickel, nickel alloys, iron, cobalt and steel. A brazing mixture is contained in the metal tube and comprises a particulate abrasive material selected from the group consisting of diamond particles and mixtures of diamond particles and carbide particles. The brazing mixture further contains powdered braze alloy in which one component of the braze alloy is a member selected from the group consisting of nickel, nickel alloy, silver, silver alloy, gold, gold alloy, copper, copper alloy and mixtures thereof, and in which a second component of said braze alloy is selected from the group consisting of iron, iron alloy, cobalt, cobalt alloy, tin, tin alloy, boron, silicon, chromium, chromium alloy and mixtures thereof. The diamond particles contained in the brazing mixture are coated with a material selected from the group consisting of tungsten, molybdenum, chromium, nickel, iron, cobalt, palladium, tungsten carbide, molybdenum carbide, chromium carbide and iron carbid…
