Thermal spray coating is a process used to apply a protective or functional coating onto a surface. It involves the deposition of molten or semi-molten materials onto a prepared substrate using a heat source. The resulting coating adheres to the substrate, providing various benefits such as enhanced wear resistance, corrosion protection, thermal insulation, or improved surface properties.

Here are the general steps involved in the thermal spray coating application process:

Surface Preparation: The substrate surface is prepared by cleaning, roughening, or applying a bond coat if necessary. This step ensures proper adhesion of the coating to the substrate.

Material Selection: The appropriate coating material is chosen based on the desired properties and the application requirements. Common materials used in thermal spray coating include metals, alloys, ceramics, and composites.
