Supersonic spraying repair of elbow surface for lithium battery industry

       Elbow is one of the commonly used parts in conveying pipelines. It is mainly used for the connection at the bend of the pipeline to change the direction of the pipeline. The pipes used in the lithium battery industry are mostly used to transport chemical media, so the requirements for surface performance are higher.



This time wococarbide.com repaired and strengthened a batch of elbows in the lithium battery industry. Considering the corrosion and wear of the conveying medium, the thermal spraying technicians used the supersonic spraying process to spray the tungsten carbide material on the surface of the workpiece to prepare the anti-corrosion and wear-resistant coating. . As a cemented carbide production material, tungsten carbide has high hardness and is not easily soluble in chemical media such as water, hydrochloric acid and sulfuric acid. Through the supersonic spraying process, the prepared metal coating has high bonding strength and compactness. have better protection.

With the continuous development of industrial technology, the application range of thermal spraying has become wider and wider. In the repair and surface strengthening of mechanical parts, it can endow the workpiece with wear resistance, corrosion resistance, oxidation resistance, erosion resistance, heat insulation, insulation, conductivity, etc. Special functions; in addition, the selection range of spraying materials is relatively wide, and it is not limited by the overall material. Combined with the thermal spraying process, high-performance functional coatings such as cemented carbide, various ceramics, and metals can be obtained. The precious materials used are relatively small, so the cost will not increase significantly. Therefore, the application of the thermal spraying process can not only effectively improve the surface strength of the workpiece, prolong the service life, but also save costs. This is an indispensable technical force for enterprises.
