What is Thermal Spray?

Thermal Spraying, various type of coating processes in which finely divided metallic or non-metallic materials are deposited in a molten or semi-molten condition to form a coating. The coating material may be in the form of powder, ceramic rod, wire, or molten materials.

The noteworthy advantage is the low substrate temperature which did not alter the base metal properties or very minimum distortion as compared to the welding process.

The thermal spray has its distinctive plus point when it utilized in repair industries.

All of the processes heat a consumable, such as a wire or powder, and project it towards the substrate. The key differences are the heat source and the particle speed before it hits the substrate. The process used has a pronounced effect on the quality of the coatings produced, but each has its distinct advantages.
