Description

Caterpillar wear-resistant layer plasma spraying processing device Technical Field The invention relates to the technical field of plasma spraying, in particular to a caterpillar wear-resistant layer plasma spraying processing device. Background The plasma spraying processing device for the track wear-resistant layer is special equipment which is specially used for preparing high-performance wear-resistant coatings on the surfaces of key parts of engineering machinery (such as track shoes, pin shafts and the like of vehicles such as an excavator, a bulldozer and the like). The technology takes the plasma jet as a core heat source, utilizes the generated high-temperature high-speed jet to instantly heat wear-resistant materials such as ceramics, cermets and the like to a molten or semi-molten state, and accelerates the injection to the surface of a workpiece to form a coating with high bonding strength and excellent wear resistance, thereby remarkably improving the service life and reliability of the crawler system under complex working conditions. The plasma spraying technology has become one of the important means for improving the surface performance of caterpillar components due to the advantages of stable coating quality, wide material application range and the like. In practical applications, workpieces such as track shoes generally need to be sprayed and reinforced on a bearing surface in contact with the ground.
