Abstract
A brazing rod for use in depositing an abrasive metal coating on a metal substrate. The brazing rod comprises particulate abrasive material selected from the group consisting of diamond particles and mixtures of diamond particles and carbide particles and a matrix comprising a braze alloy which is sufficiently sintered together to bind the particulate abrasive material into a rigid rod. The braze alloy contains one component selected from the group consisting of nickel, nickel alloy, silver, silver alloy, gold, gold alloy, copper, copper alloy and mixtures thereof, and a second component 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 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 carbide. The carbide particles are selected from the group consisting of tungsten carbide, molybdenum carbide and chromium carbide.
