Chemical nickel treatment plays a major role in the mining industry

SendTime:2018-7-31

The method of electroless nickel is used for coating. Compared with electroplating, it is energy-saving and environmentally friendly. It is easy to use and has a uniform coating. It also has a good effect on the coating of irregular articles. Nickel-phosphorus plating can not only improve performance but also improve appearance. Reflect different colors.

Chemical nickel is the surface treatment of objects. It is used in various industries and is a good way to protect the surface of objects from corrosion and maintain their long-term good performance. There are many ways to coat, the most important thing is to meet the needs of use, and to achieve sustainable development in combination with the concept of energy saving and environmental protection.

Chemical nickel is used in a wide range of applications, and it is more practical than other surface treatment methods. After electroless nickel plating, there is no gap and no corrosion, so it can be used in harsh environments.

Take the mining industry for example. The environmental conditions are poor, and the downhole machinery inevitably comes into contact with salt water and mineral acid to withstand the test of corrosion and wear. Therefore, mining machinery requires surface protection. Especially in some open pit mining production, corrosion and erosion problems are quite serious, but if electroless nickel plating is used, corrosion of parts can be avoided and the service life can be extended. Previously, hard chrome plating was used to protect the equipment, but the surface of the protective layer was cracked, porous, easily corroded, and damaged the protective layer. This problem of high pressure hydraulic cylinders is even more serious. Under high pressure operation, the coating is stretched, which further exacerbates the crack of the high internal stress hard chrome layer.

In this case, a high-phosphorization chemical nickel layer with a compressive stress of 25 um is used for protection. When the hydraulic struts are subjected to high-pressure drawing, the chemical nickel layer does not cause cracks, and corrosion resistance and wear resistance. Strong. The corrosion resistance of electroless nickel plating is well applied in the mining industry, and it is also a good protection for mining machinery parts, and it is worth promoting.
