What is Thermal Spray

Thermal Spray is a generic term for a group of coating processes used to apply metallic and non-metallic coatings. These processes are grouped into three major categories; plasma, electric arc and combustion spray. These energy sources are used to heat the coating materials (in powder, wire and rod form) to a molten or semi-molten state. The resultant heated particles are accelerated and propelled towards a prepared surface by either process gasses or atomization jets. Upon impact, a bond forms with the surface and subsequent particles cause thickness buildup.
