The nozzle needs to withstand the erosion and corrosion of high-temperature, high-pressure and high-speed combustion gases, so it needs to have sufficient strength, rigidity and heat resistance. Thermal coating is one of the important means to improve nozzle performance and reliability. By spraying a layer of high-temperature resistant, anti-oxidation and anti-corrosion coating on the outer surface of the nozzle, the erosion of the nozzle material by the combustion gas can be reduced, the service life of the nozzle can be extended, and the manufacturing and maintenance costs can be reduced.
