When the centrifugal pump impeller conveys the medium containing solid particles, the surface is washed at high speed; The sealing surface of the valve is subjected to mechanical friction during repeated opening and closing; The reactor agitator runs for a long time in corrosive media, and the metal surface is constantly eroded. These losses not only affect equipment performance, but can also pose safety hazards

Supersonic tungsten carbide thermal spraying technology provides an innovative solution to these problems. This technology forms a dense protective layer of tungsten carbide on the surface of the device, which is like a "protective coat" for the equipment. The surface hardness of the sprayed parts has been greatly improved, the wear resistance has been significantly enhanced, and the particle erosion and chemical corrosion can be effectively resisted, which is especially suitable for the protection needs of petrochemical equipment.

The process flow of this technology is scientific and rigorous: firstly, the surface of the substrate is sandblasted to ensure good adhesion; Then, the supersonic flame spraying process is used to evenly spray tungsten carbide powder on the surface of the workpiece; Finally, precision machining is carried out to ensure that the coating thickness and surface finish meet the requirements. The whole process does not affect the properties of the substrate and imparts excellent wear resistance to the surface.

Compared with traditional processes, tungsten carbide spraying has multiple advantages: the coating is firmly bonded to the substrate and has a long service life; The coating formula can be adjusted according to different working conditions. This technology is becoming an important means of extending the life of petrochemical equipment, providing new technical support for the industry to achieve cost reduction and efficiency increase.
