Application of Thermal Spraying in Aero-Propulsion

Thermal spraying technology is a surface engineering technique that involves melting or partially melting materials at high temperatures and then rapidly spraying them onto a substrate surface to form a coating. Its primary goal is to impart properties such as wear resistance, corrosion resistance, thermal insulation, and oxidation resistance to the substrate material, thereby extending equipment lifespan and improving operational efficiency. As aerospace technology accelerates toward higher performance, lighter weight, longer service life, and greater environmental friendliness, thermal spraying technology—thanks to its broad material compatibility, high process flexibility, and cost-effectiveness—has become one of the core technologies supporting the research, development, and maintenance of next-generation aircraft.
