Embodiments disclosed herein relate to the production of bulk amorphous metal (BAM) alloys comprising chromium, manganese, molybdenum, tungsten, silicon, carbon, boron, and the balance of iron to replace tungsten carbide-based welded material. The BAM alloy embodied herein can be applied through PTA welding, HVOF, TWAS, flame spraying, plasma spraying, laser, their combinations, and other coating and welding processes. When used as welded material, the density of the embodiment of around 7 grams per CC, which is less dense than the tungsten carbide customarily used, resulting in even hard faces during welding spread uniformly across the weld, therefore creating a harder and more wear-resistant weld.
A composition comprising an amorphous alloy that is free of tungsten carbide, the amorphous alloy having (i) a density that is less than that of the tungsten carbide and (ii) a wear resistance in ASTM G65 that is equal to or more than that of the tungsten carbide.
A coating comprising a composition comprising an amorphous alloy that is free of tungsten carbide, the amorphous alloy having (i) a density that is less than that of the tungsten carbide and (ii) a wear resistance in ASTM G65 that is equal to or more than that of the tungsten carbide.
