= Thermal spraying
{wiki=Thermal_spraying}
Thermal spraying is a versatile surface engineering technique used to apply a coating to a substrate to enhance its properties such as wear resistance, corrosion resistance, and thermal protection. The process involves generating a spray of molten or semi-molten materials (called feedstock) that are propelled onto the surface of a substrate. Once these particles impact the substrate, they cool and solidify, forming a coating that adheres to the surface.
