Electroless nickel plating is one of the most popular kinds of surface treatment for metals, providing a range of advantages from improved corrosion resistance to increased aesthetic appeal. Understanding it better will let you decide if it would be beneficial to you.
The electroless nickel plating process
The electroless nickel plating process is a way of attaching a nickel alloy, often also containing phosphorus, to a metal surface, creating a protective coating. This is done by submerging the surface in a chemical solution. Unlike electroplating, there is no requirement for an electric current. The phosphorus may constitute anywhere from 2% and 14% of the final product.
Benefits of electroless nickel plating
Unlike electroplating, the kind of electroless nickel plating offered at https://www.swmf.co.uk/surface-coatings/electroless-nickel-plating/ provides a coating of uniform thickness, even if the surface has holes, corners or other awkward shaping. Once treated, the smooth surface will have increased durability and hardness, being resistant to wear and corrosion.
This will extend the item’s overall lifespan, which will reduce maintenance, repair or replacement costs. The final appearance will be impacted by the amount of phosphorus the coating contains, but it will often lead to a brighter, more aesthetically pleasing finish. This combination of benefits mean electroless nickel plating is sought after in many industries, including aerospace, automotive, medical, manufacturing, electronics, food processing and oil and gas extraction.
There are situations where other forms of finish may be more appropriate for your purposes, but electroless nickel plating has a wide range of benefits, which explains why it is utilised in so many different industries.
