What is Thermal Spraying?

Thermal spraying refers to a process that applies a coating - most often a metal alloy, carbide or ceramic (that may vary in thickness) onto a substrate through the projection of a molten stream of the material.

Invented in the early 1900s, thermal spraying was a very simple process and was generally used to perform very basic mechanical repairs. Over the years, the technology has undergone rapid growth, and today, thermal spraying has become a very powerful tool, finding a wide range of applications in virtually every industry.

Thermaspray is constantly reviewing its processes to ensure that OEM and end-user customers receive a cost-effective, top quality service using the latest technologies available.

Value to Thermaspray Customers

OEM customers benefit through the use of thermal spray coatings that improve the wear and corrosion resistance of critical surfaces in the equipment they supply, thereby extending the service life and reducing the life cycle cost of their equipment.

For end-user customers, Thermaspray's coatings are used to refurbish components subjected to degradation by wear, corrosion, oxidation or cavitation, all of which result in reduced service life. This process improves the performance and extends the service life of components.

Thermaspray's leading coating technology solutions also make it possible to modify the surface of engineering components to provide unique functional properties, such as non-stick, low or high friction, and electrical or thermal insulation properties.

What are the Benefits of Thermal Spraying?

  • Extended service life through the restoration of worn components to original dimensions
  • Increased wear resistance against erosion, abrasion and sliding
  • Increased resistance to cavitation
  • Increased resistance to chemicals and corrosion
  • Increased resistance to high temperatures and oxidation
  • Increased traction

What Thermaspray Offers

Thermaspray leads the field in providing advanced coating solutions, and our team is well qualified to provide customers with a wide range of specialised industrial coatings.

Prior to the coating process, surface preparation is essential to ensure a quality finished product. This process could require pre-machining to remove damage, cleaning, de-greasing and surface roughening using a variety of grit blasting techniques able to handle varying component sizes and geometries.

Thermaspray's coating processes are applied using very impressive 6-axis robotic gun manipulation, and include:

  • High Velocity Oxy-Fuel (HVOF)
  • Plasma spray
  • Electric arc spray
  • Combustion wire spray
  • Powder flame spray
  • Spray and Fuse
