Abstract: 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.

Abstract: An embodiment relates to a material comprising a ceramic formed from an amorphous metal alloy (amorphous metal ceramic composite), wherein the composite exhibits a higher corrosion resistance than that of Haynes 230 when exposed to molten chlorides such as KCl or MgCl2 or combinations thereof at temperatures up to 750° C. Yet, another embodiment relates to a method comprising obtaining a substrate, forming a coating of an amorphous metal alloy, heating the coating, and transforming at least a portion the amorphous metal alloy into an amorphous metalceramic composite.
