Profile: Astro Alloys, Inc. specializes in HVOF equipment and thermal spray powders. We offer TAFA® arc thermal spray systems and equipment, which are engineered to maximize simplicity, durability, and repeatability regardless of coating application. This process involves two wires that are fed into the gun, they are then charged and an arc is generated between them. The heat from the arc melts the incoming wire and the molten feedstock is then deposited on the substrate. The arc spray process is used in the power generation industry for coatings that provide corrosion protection, part restoration, and life extension.
