Description

Technical Field

[0001] The utility model relates to the field of thermal spraying equipment, in particular to a metal material thermal spraying equipment. Background Art

[0002] Automotive parts are subject to constant friction and wear during use. Thermal spraying equipment can create a high-hardness, wear-resistant coating on the surface of these parts. For example, spraying a wear-resistant coating on components like engine piston rings and camshafts can significantly extend their service life. As the piston moves up and down within the cylinder, friction between the piston ring and the cylinder wall is significant. Thermal spraying wear-resistant materials like tungsten carbide can significantly reduce piston ring wear, ensuring engine performance and reliability.

[0003] Taking the SX-8000 thermal spray equipment as an example, it mainly includes a gas safety center, an intelligent dual powder feeding system, a PLC intelligent control system, a supersonic spray gun and a chiller; taking the supersonic spray gun as an example, the supersonic spray gun is usually heavier. During the spraying process, for some spray materials with a high melting point or high viscosity, such as ceramic particles, the fluidity of this material inside the spray gun will be reduced when spraying, and the material cannot be sprayed out more smoothly from the nozzle, and cannot form a uniform coating on the workpiece surface, which reduces the spraying quality.
