What fields can supersonic spraying be applied to? How to maintain supersonic spraying equipment?

The following is an introduction to the application field and equipment maintenance methods of supersonic spraying:

Application areas of supersonic spraying

aerospace field

Engine components: Supersonic spraying of blades, combustion chambers, and other components of aircraft engines can improve their high temperature resistance, wear resistance, and corrosion resistance, extend their service life, and ensure reliable operation of the engine under harsh conditions such as high temperature, high pressure, and high-speed rotation.

Aircraft structural components: Spraying wear-resistant and anti-corrosion coatings on structural components such as landing gear and wing connections can enhance the surface performance of structural components and improve the overall safety and reliability of the aircraft.

Automotive industry field

Engine components, such as piston rings, valves, cylinder liners, etc., can be coated with wear-resistant and anti friction coatings through supersonic spraying to reduce friction losses, improve engine efficiency and durability, and reduce fuel consumption and exhaust emissions.

Chassis components: Spray anti-corrosion and wear-resistant coatings on the transmission shaft, half shaft and other chassis components of the car, which can effectively resist the erosion and wear of road moisture, dust and other factors, and extend the service life of the components.

Mechanical manufacturing field

Mold manufacturing: Spraying hard coatings such as tungsten carbide on the surface of the mold can improve its hardness, wear resistance, and demolding performance, reduce mold wear and corrosion, improve the service life and production efficiency of the mold, and ensure the quality of product molding.

Shaft parts: For various rotating shaft parts such as motor shafts, machine tool spindles, etc., supersonic spraying can be used to repair worn parts, improve the surface hardness and wear resistance of the shaft, and ensure the accuracy and stability of the shaft.

Petrochemical industry

Pipeline anti-corrosion: Spraying corrosion-resistant coatings on the inner walls of oil and gas transmission pipelines can effectively prevent the corrosion of pipeline inner walls by oil and gas media, extend the service life of pipelines, reduce leakage risks, and ensure the safe operation of pipelines.

Reactor lining: Ultrasonic spraying of ceramic coatings on the inner walls of chemical reactors can improve their corrosion resistance, high temperature resistance, and wear resistance, meeting the process requirements of different chemical reactions.

Electronic and electrical field

Electronic components: Spraying insulation or conductive coatings on the surface of electronic components can achieve insulation protection or improve their conductivity, thereby enhancing the reliability and stability of electronic components.

Electrical equipment: Spraying on the busbars, contacts, insulators and other components of electrical equipment can improve their surface insulation, oxidation resistance and conductivity, ensuring the safe operation of electrical equipment.

Maintenance methods for supersonic spraying equipment

routine maintenance

Cleaning equipment: After each use, dust and powder residue on the surfaces of components such as spray guns, powder feeders, and gas pipelines should be promptly cleaned to prevent powder accumulation from affecting equipment performance.

Check components: Check whether the nozzle, electrodes, and other components of the spray gun are worn, blocked, or damaged. If there are any problems, they should be replaced or repaired in a timely manner. At the same time, check the wear of the powder feeding wheel, scraper and other components of the powder feeder to ensure uniform and stable powder feeding.

Gas system maintenance: Check whether there are leaks in the gas pipeline, whether the filter is clogged, replace the filter element in a timely manner, and ensure the purity and pressure stability of the gas.

regular maintenance

Equipment calibration: Regularly calibrate the spraying parameters of the equipment, such as spraying power, gas flow rate, powder feeding speed, etc., to ensure stable spraying performance and consistent coating quality of the equipment.

Component replacement: Regularly replace vulnerable components such as the nozzle, electrode, sealing ring of the spray gun, as well as the powder feeding tube and valve of the powder feeder, based on the frequency of equipment use and the wear of the components.

Electrical system inspection: Check the electrical system of the equipment, including whether the wire connections are loose, whether the electrical components are aging, etc., promptly eliminate electrical faults and hidden dangers, and ensure the electrical safety of the equipment.

Long term storage and maintenance

Cleaning and drying: Before long-term storage, the equipment should be thoroughly cleaned of powder and impurities inside and on the surface, and dried to prevent moisture and rust.

Sealing protection: Key components of the equipment, such as spray guns, powder feeders, etc., can be sealed and protected with oil seals or rust inhibitors to prevent rusting and corrosion of the parts. Meanwhile, store the equipment in a dry and well ventilated warehouse to avoid collisions and damage.
