Nickel is the chemical element Ni. It is a silver-white metal with a golden tinge that is capable of withstanding corrosion, even at high temperatures. It is frequently used to plate other metals, in order to protect and strengthen them.
Electroless nickel coating allows surfaces to be deposited with a nickel coating, without the use of an electric current. This process is normally completed in an acid bath where chemical reactions take place.
How to maximise performance:
1. Parts should be chemically pretreated and rinsed to remove surface contaminants.
2. Water purity in the EN bath should be checked thoroughly.
3. The tank holding the EN bath should ideally be of stainless steel or polypropylene construction.
4. A filtration of 4-5 turnovers per hour is recommended within the plating bath. This removes insoluble materials and prevents substrate roughness.
5. Throughout the plating process, the temperature in the plating bath should be monitored closely. This helps to prevent blistering or coating deposition.
Electroless nickel coating
A specialist provider can offer a coating service, using state-of-the-art facilities and utilising the latest innovations in technology.
The purely chemical, electroless nickel coating process ensures the even distribution of plating, even in corners and hard-to-reach areas.
A specialist provider can offer a range of nickel-plating options, such as low, medium, graded medium, and high phosphorus protection, based on your specific industrial needs. There is also the provision of specialist services such as non-stick nickel coating, which combines PTFE and nickel combinations.
