First, the characteristics of the technology:
1. Non-toxic, non-polluting and environmental protection are important features of this electroless nickel plating technology;
The electroless nickel plating solution developed is non-toxic and odorless, and does not pose a hazard to the human body during production and use, and does not pose pollution to the environment.
2. The hardness of the coating on the surface of the workpiece is increased;
Comparison of hardness before and after electroless plating of metal materials:

3. The corrosion resistance of the workpiece after chemical plating is improved;
The surface of the workpiece treated by the technology is an amorphous alloy. In the dilute phosphoric acid, sulfuric acid or hydrofluoric acid, the corrosion resistance of the alloy layer is lower than that of the hard chrome plating, which is not easy to corrode.

4, good profiling. Compared with electroplating, this technology has no excessive tip current density, and there is no excessive thickening at sharp corners or edge projections, and no grinding is required after processing.
5. The surface of the coating is uniform, without defects such as pitting, cracking, foaming, etc., and a uniform alloy layer can be obtained in the blind hole, the pipe member and the inner surface thereof.
6, strong combination. Its hardness and wear resistance are higher than the plating layer.
7, the thickness of the coating can be controlled;
8, the process is simple. No DC power supply is required, and the workpiece to be processed has no conductive contact. Only the immersion of the workpiece in the electroless plating solution for about 1 hour can obtain an alloy layer with excellent physical, chemical and mechanical properties, and the production operation is very simple.
9. The investment is small. The investment is much smaller than building an electroplating plant, and small-scale production requires only 100,000 yuan in equipment investment.
10, no need to be highly knowledgeable, easy to learn, easy to master.
Second, the application range Because the chemical coating has good uniformity, hardness, corrosion resistance and wear resistance and other comprehensive physical and chemical properties, can be applied to aviation, aerospace, automotive industry, chemical industry, information industry, petrochemical industry, mining industry , textile industry and civilian hardware products. The petrochemical industry can be used for pipelines (oilfield drilling), pump casings, sucker rods, ball valves, piston pumps, packers, mud pumps and blowout preventers.
Third, the technical advantages 1, the surface of the coating is bright and shiny, is an important advantage of the electroless nickel plating technology;
Metal surface electroless plating is a well-known technique and has been industrially produced. However, the surface of the existing manufacturers is generally gray, dull and not bright. This technology has studied a special brightener, which is added to the electroless plating bath without polishing, which can make the surface of the coating appear stainless steel color, which is the unique technical feature of the technology;
2. Providing users with the technology of recycling and recycling electroless plating waste liquid is another significant feature of the transfer of this technology.
For users who use this electroless nickel plating technology, a calculation method can be taught to make the electroless plating waste liquid fully recovered and reused to reduce the production cost. This is also different. The current manufacturer's practice is based on experience. Add plating solution without accurate calculation process.
