The Thermal Spray Association of Southern Africa
The Thermal Spray Association of Southern Africa(TSASA) is a committee supported by the Southern African Institute of Welding (SAIW). TSASA is a professional association that is dedicated to the expansion of the Thermal Spray industry and, to the benefit of the industry and society.
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.
WHAT CAN WE DO WITH THERMAL SPRAY?
- Improve/change the surface of the material.
- Repair and refurbish worn components.
- Provide corrosion protection.
