Plasma spraying is a technique for surface strengthening and modification. A DC arc-driven plasma arc is used as a source to heat the metal or ceramic powder to a molten or semi-molten state, and to spray the workpiece at a high speed. When used in plasma spray guns, our nozzles and electrodes have to withstand temporary temperatures of more than 10 000 °C.

    Combined with our company's unique BACK-CAST technology, we are able to achieve particularly reliable tungsten-copper connection. The tungsten-copper has good heat dissipation and excellent resistance to arc erosion. As a result, our nozzles and electrodes guarantees a long service life.

    We offer plasma spray nozzles and electrodes for a wide range of 9MB, F4 and other spray guns from Metco, GTV, FST and more. And we are also happy to supply tungsten-copper semi-finished products.
