There are many ways to add a protective layer to a surface. Electroless nickel plating is one of them, and it is chosen over others for specific reasons that you should consider when weighing the most appropriate approach for your purposes.
What is electroless nickel plating?
Electroless nickel plating such as that found at //www.poeton.co.uk/surface-treatments/plating/electroless-nickel-plating/ is a method of attaching a thin layer of nickel to a surface, thereby increasing its hardness, corrosion resistance and general durability. It relies on immersing the surface in a chemical solution, as opposed to utilising an electric current as in electroplating.
Consistency
One of the most notable advantages of electroless plating is the ability to create a uniform coating, one that is the same thickness across the entire surface. Electroplating is often unevenly dispersed around edges, corners and holes, and may require additional processes to ensure consistency.
Tolerance
Tight tolerance is another advantage conveyed by the uniform thickness of an electroless nickel coating. Indeed, its tolerance measures favourably compared to a thermal spray coating in particular.
Hardness
It is usually important that a plated surface is stronger and harder than the substrate alone. Electroless nickel plating scores highly on the Rockwell scale of hardness. It does not seize or gall, and in some situations may even be compared to chrome plating.
Not every surface will benefit from electroless nickel plating over other forms of surface treatments, but in certain circumstances, it presents clear advantages over other approaches, particular when you need a uniform coating that is particularly strong and durable, with tight tolerances.
