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. In the spray gun,  the electrode are subjected to extremely high temperatures. The high melting point of tungsten and the high thermal conductivity of the copper material make the nozzle and the electrode to obtain excellent arc corrosion resistance, high temperature resistance and optimum thermal conductivity.

Our company uses back-casting method to realize nondestructive combination of tungsten and copper, and obtain stable and reliable connection of tungsten and copper.
