Have you ever wondered how electroless nickel plating works? We take a brief look at this process as well as some of the key benefits of it in comparison to electrolytic options. We also look at some of the most common ways that it is used.
The Electrolysis Process
Unlike electrolytic nickel plating, this process requires no electrical current. To begin the process, the object is cleaned with chemicals and then rinsed in water. This is often carried out a number of times to ensure the surface is completely free of dirt or soil. Then it is dipped into a water-based solution that contains a reducing solution such as sodium hypophosphite along with nickel salts. This reducing agent removes the need for an electric current, which is used in traditional nickel plating. The nickel salts and reducing solution cause a chemical reaction that results in an even layer of metal being deposited on the surface of the object. Electroless nickel plating is a specialist process that is carried out by companies such as www.poeton.co.uk/surface-treatments/plating/electroless-nickel-plating/.
The Benefits
This process of electroless nickel plating offers a number of advantages over electrolytic nickel plating. Notably, it creates a more even finish than an electrolytic process. It also requires less apparatus, and there is no need to use electric power. It will also result in a less porous surface, which will be less prone to corrosion and more resistant generally. It is also non-magnetic and can produce a range of finishes, including matte, semi-matte or shiny.
Common Applications of Electroless Nickel Plating
Due to its corrosion-resistance, this type of finish is suitable for parts that are used in extreme conditions, such as in marine, aerospace and defence industries. It can also be found in fixtures such as door handles, circuit boards and hard drive disks.
This electricity-free nickel plating process uses chemicals to apply an even coating of nickel to a range of objects. The many advantages of electroless nickel plating include corrosion resistance, making it an excellent choice for use in specific industries such as aerospace and defence.
