The gun employs an electric arc to melt the wires and an HVAF jet to atomize and accelerate the fused particles. The spray head, which is the size of a conventional arc head, includes a toroidal combustion chamber atomizer surrounding the wire tips. A hot ceramic insert activates air-fuel combustion and makes it stable within an extremely short chamber. Exhaust gases are directed into the arc zone. The resultant high velocity jet atomizes molten material, accelerates particles, and propels them toward the substrate where they form a coating. This jet is low in oxygen content and protects the liquid metal from oxidation in the arc zone. Dense, very fine structured coatings with an even distribution of elements and phases are formed due to the atomization of spray wires to extremely fine particles, their acceleration to high velocities, and in-flight protection against oxidation. While this is beneficial to all sprayed materials, the TurboArc gun demonstrates exceptional performance while spraying cored wires. Hard-face coatings of such wires exhibit improved resistance to erosive and abrasive wear, and in many applications they can replace hard chrome plating. TurboArc can be ordered in a high feed rate (HFR) configuration that is optimized for materials with low melting points, such as zinc and aluminum.
