Nickel plating is a practice whereby a material is given an additional metal layer in order to provide a desired attribute. These will vary by industry, but can cover improved resistance against wear or corrosion, added strength, resistance to friction, an aesthetic boost, or simply repair work.
During the manufacturing process, there are plenty of routes to take regarding nickel plating. Depending on what you need, the process of nickel plating will also vary. Do you value aesthetics above all else, or are you seeking some added durability or corrosion resistance?
Bright nickel plating
For bright nickel plating, an electric current is used to apply a shiny, mirror-like sheen to a product. This can improve conductivity, but may not be as strong or resistant as other methods. This method is ideal for restoring worn-down mechanisms, but is also generally a great choice for aesthetics.
Electroless plating
On the other hand, electroless nickel plating is a great choice due to the more precise coverage that chemical reactions can provide. You’ll receive a more even, uniform coating with electroless plating, which can be essential for more precise workloads.
The method is slightly more expensive, and electroplating is typically better for bulk production, but electroless plating is undoubtedly the highest quality practice available. You can find out more or reach out for services online, such as at www.swmf.co.uk/surface-coatings/electroless-nickel-plating/.
Dull nickel plating
The counterpart to bright nickel plating, this variation adds a matte finish to a product. Not to say that duller means less aesthetic, but this option definitely prioritises strength and durability above looks.
This is a great choice for coatings that will need to withstand significant levels of wear and corrosion, making it ideal for frequent abrasion, friction, and weathering. It’s especially helpful for moving parts, helping join applications together, or even simple things like springs. Your choice of plating will vary depending on what you’re after, but to summarise with some general rules of thumb: bright plating for repairs and aesthetics, electroless for the highest quality, and dull plating for resistance above all else.
