Supersonic spraying of tungsten carbide coating on the surface of turbine bracket

       Supersonic spraying tungsten carbide coating is one of the commonly used wear-resistant coatings. The wear-resistant coating is mainly to reduce the wear of equipment parts, and to coat a layer of wear-resistant materials on the surface of equipment parts to protect the substrate. Wear-resistant coatings are widely used, and workpieces with high requirements for wear resistance in mechanical operation can be surface-strengthened by thermal spraying, regardless of size.

Workpieces such as between turbine brackets have relatively high requirements for wear resistance, and surface wear is one of the damage methods. When Tianmeng company repairs and strengthens the surface between turbines, it combines the requirements of its working conditions. As well as the basic material conditions, the supersonic spraying process is generally used to spray tungsten carbide coating on the surface. Tungsten carbide is often used in the preparation of wear-resistant coatings because of its hardness, which is second only to diamond. The flame velocity of supersonic spraying is relatively high, so the prepared coating has relatively high compactness and bonding strength, and the porosity is small.

With the continuous increase in the cost of industrial raw materials and the continuous development of new coating materials and processes, the application of thermal spraying technology has become more and more extensive. It can not only repair damaged mechanical workpieces, but also endow workpieces with new functional coatings. The scope of application in the field of additive manufacturing is also gradually expanding, improving the efficiency of industrial development, and the industry has also saved a lot of energy and materials, reducing production costs.
