There are many types of metal finish, each with its own distinct advantages and disadvantages. Trying to choose the one that is most suitable for your needs can be challenging and requires careful consideration of a range of factors.
Why do people choose metal finishes?
People use metal finishes to try and add to or enhance the properties of a surface. They may be trying to add durability, wear resistance or corrosion resistance. They may be trying to improve its ability to conduct electricity. Sometimes, it is simply an attempt to improve its aesthetic quality by creating a smoother, shinier or differently coloured surface.
Choosing between metal finishes
Considerations when choosing a finish include intended purpose, speed, cost and safety. Electroless nickel plating such as that at //www.swmf.co.uk/surface-coatings/electroless-nickel-plating/ does not require a power source to provide an electrical current like electroplating, and it can work on non-conductive metals. It also allows more evenly distributed coatings, and is better for more complex shapes and corners. Its weakness is when a thicker coating is required. In these situations, electroplating may be the preferred choice.
Electroplating is also generally quicker than electroless plating and, despite the power cost, uses less expensive chemicals. Other variations include trivalent chrome plating, which reduces the risk to the environment and human health found in traditional chrome painting, and paint-over-chrome, which allows translucent and opaque finishes, and a wider range of colours.
Weighing the features of different types of metal finish will allow you to decide which method is most suited to your purposes.
