What is Galvanisation?
When a metal is galvanised, a protective zinc coating is applied to it. This zinc coating is applied to steel or iron in order to prevent the surface of the metal from rusting. Hot-dip galvanisation is the most common method of galvanisation. During this process, the steel parts are submerged in a bath of molten zinc. This process is also achievable through electrochemical and electro deposition processes but there are some differences between them.
Electroless Nickel as an Alternative to Galvanisation
Electroless nickel plating and galvanisation are both effective metal finishing techniques for the prevention of corrosion and rust on the surface of metal. If you’re trying to decide which would be a better coating for your application, here are 3 reasons why you should choose electroless nickel plating as an alternative to galvanisation.
Durability and Corrosion Resistance
The electroless nickel plating process is a high quality, cost effective solution to coating metals such as mild or stainless steel and can substantially extend the life of a component. It is an excellent alternative to galvanisation as it is both durable and aesthetically pleasing.
Not only does electroless nickel plating provide enough corrosion resistance to be used in harsh environments, the uniform coating it creates can be a perfect solution for critical high-end engineering items such as those used in the defence, healthcare, automotive and aerospace industries.
Electroless nickel plating is also much cheaper than you would imagine, considering the extent of its durability, and the wear resistance of the surface can be increased by using heat treatments. This makes it an ideal specialist plating where friction and wear may be problematic with regard to the use of the component.
