Why choose Electroless Nickel? Electroless Nickel is a superior corrosion-resistant metal that exhibits good resistance in alkaline and neutral environments. Below this pH, the corrosion rate increases rapidly. However, high temperature heat treatments can compromise its corrosion resistance and cause internal stresses and microcracking. Fortunately, electroless nickel’s resistance to corrosion is enhanced by heat treatment above 500 degrees. Compared to steel, nickel has more noble properties and a high phosphorus content, making it highly resistant to corrosion.

It is more efficient than other plating processes. The electroless nickel plating process involves several finishing operations, including blasting and tumble finishing. In addition, electrolytic strikes and immersion preplate deposits are also used to improve electro nickel deposition rates. Finally, post-plating baking is used to improve adhesion. Those are just a few of the reasons why electroless nickel coatings are a superior option.

Electroless nickel offers superior uniformity. While it is prone to tarnishing, it is more resistant to corrosion than chrome. This makes it a better choice for parts that are difficult to reach and are exposed to high temperatures. It also offers an extended working life. With these advantages, electroless nickel plating is a more popular choice among manufacturers of various products. But there are still some important considerations.

Because of the uniformity of electroless nickel deposits, complex shapes and patterns can be plated without worrying about their imperfections. For example, electroless nickel has been used to plate industrial diamonds as small as 125-grit.

Electroless Nickel plating also provides improved corrosion resistance and electromagnetic interference shielding. These properties are essential for applications that involve electronics, such as electronic components. As a result, these coatings are extremely hard.

Another reason to choose electroless nickel plating is the cost-effectiveness. Electroplating requires huge amounts of electricity, and is also dangerous. Electroless nickel plating requires less electrical energy and provides a high-quality finish. Moreover, electroless nickel plating eliminates the need for additional coatings and saves money on utility costs. Furthermore, electroless nickel plating allows for greater precision, and the ability to customize thickness.

The electroless nickel plating process deposits a layer of an alloy made up of 90 percent nickel and 10 percent phosphorus. Electroless nickel plating is highly resistant to galling and is an excellent choice for non-conductive objects. Electroless nickel plating also offers exceptional corrosion protection. The process involves a series of steps, each critical to a high-quality finish. Depending on the substrate, these steps may vary slightly.
