Plasma coating

The plasma coating transforms ionization of
air (arc, hydrogen, nitrogen, and helium)
into high heat. The center temperature reach
30000°k, and the temperature from the
nozzle stands at between15000～20000°k。

Merits of plasma coating：
1. Super high temperature to conduct coating
of high fuel point materials
2. High speed of injection particles to ensure
dense and high sticking coating.
3. Coating materials are not easy oxidation.
