The non-destructive combination of tungsten and copper of plasma nozzle and electrode are the core components of the plasma spray gun, mainly used for plasma arc to melt the spray powder and accelerate the spray. Plasma spraying is the most widely used thermal spraying technology, which produces coatings with good performance, long service life and high reliability.
Plasma spraying is used to apply ceramic, cermet or metal coatings in several industry sectors. These coatings are designed to provide wear and corrosion protection, or to give functional properties such as thermal barrier or thermal insulation advantages.
