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. 

Our Objectives

Ensuring that the members of the organisation receive tangible benefits.
Focus on safety improvements for both the operators and the environment.
Engaging with research and Development organisations in Southern Africa.
Developing a certification program and enforcing standardisation of approvals/standards (for those who need and use them for local and/or international markets).
Develop, integrate advisory programme applications within every industry sector, starting with the following: Mining, Power Generation, Oil and Gas, Metal Processing, Infrastructure( Anti-corrosion), Aerospace, Paper, Pulp and Printing.

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.


  • Improve/change the surface of the material.
  • Repair and refurbish worn components.
  • Provide corrosion protection.
