What is the current application status of supersonic spraying technology in the industrial field?

Supersonic spraying technology is widely used in the industrial field, and its specific application status is as follows:

aerospace field

The high-temperature components of aircraft engines, such as turbine blades and combustion chambers, can be effectively reduced in surface temperature by supersonic spraying of ceramic thermal barrier coatings, improving the thermal efficiency and reliability of the engine, and enabling it to operate stably under extreme conditions such as high temperature, high pressure, and high speed. In addition, the landing gear is coated with wear-resistant and corrosion-resistant coatings to enhance its wear and corrosion resistance, ensuring flight safety.

Energy and power sector

In thermal power plants, boiler pipelines often face high-temperature corrosion and erosion problems. The anti-corrosion coating formed by supersonic flame thermal spraying can effectively protect the pipelines and reduce maintenance and replacement frequency. In the field of wind power, spraying coatings on the surface of wind turbine blades can improve their weather resistance and wear resistance, extend the service life of the blades, and thus improve power generation efficiency.

Mechanical manufacturing field

The pistons, crankshafts, and other components of automobile engines can be coated with wear-resistant coatings by supersonic flame thermal spraying, which can reduce the friction coefficient, improve wear resistance, reduce energy loss and failures caused by wear, and improve the reliability and efficiency of the entire mechanical system. In addition, various molds, shaft parts, etc. often use supersonic spraying technology to improve surface hardness, wear resistance, and demolding performance.

Petrochemical industry

During the drilling process, petroleum drill rods must withstand complex stress, wear, and corrosion environments underground. Supersonic flame thermal spraying tungsten carbide coating can improve the hardness and strength of the drill rod surface, enhance its wear resistance and corrosion resistance, reduce the wear of the drill rod during drilling, prevent accidents such as drill rod rupture caused by corrosion, and reduce the cost of petroleum drilling. The reaction vessels, pipelines, etc. in chemical equipment can resist the erosion of various chemical media and improve the service life of the equipment by spraying corrosion-resistant coatings.

Paper and printing field

Paper making rollers need to withstand pressure, friction, and contact with corrosive chemicals during operation. Supersonic flame thermal spraying tungsten carbide coating can improve the hardness and wear resistance of the roller surface, enabling it to better withstand pressure and friction, reduce wear, and the chemical stability of the coating can also resist the corrosion of chemical substances, ensuring the surface quality of the roller, improving the flatness and quality of the paper, and extending the service life of the roller. The rollers in printing equipment can improve their surface wear resistance and corrosion resistance through supersonic spraying technology, ensuring printing quality.

Textile and Chemical Fiber Field

In the textile production environment of high temperature, high humidity, and strong wear, traditional metal rollers have a short lifespan and high maintenance costs. By using supersonic plasma thermal spraying with ene carbon ceramic coating, good wear resistance and corrosion resistance protection can be provided for textile rollers, extending their service life, reducing maintenance costs, and improving production efficiency. The precision retention and service life of components such as spinnerets in chemical fiber production equipment can be improved by spraying wear-resistant and corrosion-resistant coatings.
