Nickel plating is usually done for decorative purposes. Nickel-plated products surface has a higher level of adhesive than galvanized. This method also helps plating products to withstand good weather conditions, the coating is difficult to peel off.
Nickel plating methods
Electrolytic nickel plating
Electrolytic nickel plating is divided into 2 forms:
- Electrolytic nickel plating
- Electrolytic black nickel plating.
In fact nickel has a higher surface than iron, taking advantage of this advantage people use nickel plating chemicals to protect a variety of machines, devices, tools and pipes. Nickel-plated coating has the ability to help increase abrasion so it is applied to printing technology, used to plating print plates with the effect of increasing surface hardness, effective anti-corrosion.
Decorative Nickel Plating
This technology is often used in household appliances, plating medical instruments, decorative nickel plating for motorcycle parts, bicycles, automotive applications, etc. But the nickel nature is not stable when exposed to air, the polished nickel surface will be dimmed in the air. Therefore, if you want to ensure the best nickel plating on the surface of the product, you should apply many layers of Cu-Ni or Cu-Ni-Cr.
For glossy black products, people will use black nickel plating method to create shiny black. People also use the method of black nickel plating to absorb light in the making of photoelectric devices.
Chemical Nickel Plating
This is a technology that takes advantage of the precipitation layer on the surface of products that need to be plated, chemical plating is essentially redox process generated by catalyst conditions.
Advantages of chemical nickel plating technology: The plating layer on the surface of the part is uniformly thick, even with details with complex shapes, the plating layer of high hardness and hardness. It is possible to apply chemical nickel plating on surfaces of plastics, conductors, special chemical, mechanical and magnetic properties.
A special feature of nickel plating technology is rust protection for industrial equipment. Along with the characteristics of high hardness, good abrasion resistance, nickel plating is also used to plating machine parts, such as crankshaft, air compressors with the purpose of extending the service life very effectively.
