Profile: ThermoCermet specializes in providing thermal spray coatings. We specialize in abrasion protection coatings, EMI/RFI shielding and dielectric coatings. Thermal spraying is a group of coating processes in which metallic and non-metallic materials are deposited in a molten or semi-molten condition to form a coating. Coating materials include metals, alloys, carbides, ceramics, plastics, composites, and blended materials. Our plasma spray system has the ability to spray any available powder of the correct mesh size. The flexibility of the plasma spray process comes from its ability to develop sufficient energy to melt almost any coating material in powder form. The plasma gun utilizes a chamber with one or more cathodes and an anode (nozzle). With process gases flowing through the chamber, direct current power is applied to the cathode, which arcs to the anode. The powerful arc strips the gas molecules of their electrons to form a plasma plume. Thermal energy is released as the unstable plasma ions recombine back to the gaseous state. The feedstock material is injected into the hot gas plume, where it is melted and propelled towards the target substrate to form the coating. Electric arc wire spray process uses two metallic wires, usually of the same composition, as the coating feedstock. The two wires are electrically charged with opposing polarity, and are fed into the arc gun at controlled speeds.
