20th century metal spraying gunman, thermal spray technology developed very rapidly, and quickly be widely used. To the 20th century, plasma spraying is still dominant. It is noteworthy that the recruitment metal spraying, high velocity flame spraying (HVOF) spraying metal rapid development of Shenzhen, will occupy 25% of the market share, ranking second. Arc spraying technology, because the economy is good, the coating layer superior performance than flame spraying, flame spraying technology will partially replace rose to third place. Plasma Spray Description: In the high-temperature surface treatment process, when a gas such as nitrogen, argon, and helium, such as when a compressed arc formed by producing electrically neutral ionized plasma (the material outgassing, the first liquid, solid outside four-state), plasma arc energy concentration is high temperature, the temperature of its flame flow over ten thousand degrees, you can melt all the solid engineering materials. In this high-temperature plasma as a heat source to melt the coating material is prepared by coating processes such as plasma spraying. Plasma spraying thermal spray process is one of the most commonly used means. The method is particularly suitable for spraying a variety of high-melting ceramic, refractory metals and cermet spraying material.
