Application of Plasma Spraying Technology in Automotive Engine Manufacturing

Application of Thermal Spray Coating Technology in Automobiles

Thermal spraying technology is one of the most effective techniques for surface modification in the field of surface engineering. By selecting coating materials with different properties and employing various process methods, it is possible to prepare functional coatings that offer features such as wear resistance, corrosion resistance, high-temperature oxidation resistance, thermal barrier performance, catalytic activity, electromagnetic shielding and absorption, electrical conductivity and insulation, and far-infrared radiation.

Imported plasma torches (torch for spraying ceramic powder materials such as alumina, chromia, and zirconia)

The imported SG100 plasma torch is an 80-kW multiphase torch suitable for a wide range of applications. Whether you’re engaged in high-volume production requiring high-quality, uniform, and repeatable coatings or in small-batch production that demands speed and flexibility, the SG100 offers unparalleled versatility.

Application of Thermal Spraying Technology in Gas Turbine Maintenance

Gas turbine power generation is becoming a hot topic in China's power industry. Addressing the issue of China's reliance on others for heavy-duty gas turbines is both a national imperative and the shared dream of all Chinese power professionals. For a long time, developed Western countries have strictly controlled the export of high-tech products to China, and high-power gas turbine technology has undoubtedly been a key focus of their protection efforts—whether it’s the installation of new units, the maintenance of older ones, or the manufacturing and repair technologies for critical components.

Injection Molding Machine and Extruder Screw with Tungsten Carbide, Hard Alloy, and Ceramic Coating

In response to the demands of various plastic products, most of the ultra-engineering plastics currently in use contain additives such as flame retardants, glass fibers, calcium carbonate, and modifiers, which lead to rapid corrosion, wear, and shortened service life of the barrel and screw. This process ensures that the sprayed alloy layer is completely resistant to peeling, cracking, and porosity, and strictly controls issues such as workpiece deformation.

Tungsten Carbide Spraying and Processing

In the new-energy lithium-battery industry, various types of equipment—such as screw shafts, screw conveyors, battery raw-material crushers, mixers, conical hoppers, powder feeders, and feeding machines—are coated with wear-resistant tungsten carbide coatings on their surfaces.
