Five Reasons to Choose Electroless Nickel Plating

Electroless nickel plating is simpler than its counterpart electroplating process and widely used in the metal industry for finishing of complex metal parts. It offers a wide range of advantages due to the nature of the process. Let’s have a look at the key advantages of electroless nickel plating.

Coat almost anything

The major advantage of electroless nickel plating is that it can easily coat complex shaped metal parts. As standardized shapes are becoming less common, electroplating technique often unable to uniformly coat the entire surface of a metal substrate. On the other hand, in electroless nickel plating ( sun-glo/electroless-nickel ), metal parts are dipped into the plating solution. Therefore, it can easily coat complex and irregular shaped metal parts. More importantly, as no electricity required in this process, non-conductive surfaces can also be coated easily using this process.

Non-porous coating

The purpose of nickel coating is to provide protection from wear and abrasion, resistance against corrosion and add hardness to metal parts. For many years, nickel has been deposited on the metal substrate using electroplating process. Due to the nature of the process, a porous layer is deposited on the metal substrate which makes nickel coating peel easily and less resistant to water. Electroless nickel plating deposits a less porous layer than electroplating which provides a better barrier of corrosion protection to metal parts.

Uniform thickness

The major drawback of the electroplating process is that it does not form a layer of uniform thickness over the entire surface of the workpiece which results into less consistent nickel coating. Electroless nickel plating overcomes this drawback and provides an even and uniform coating across the entire surface. It provides excellent protection to the whole metal substrate against corrosion. More importantly, you have better control over the thickness of the coating in this process. The thickness of plating can be as thin as 0.0005” and as thick as 0.10”.

Cost-effective coating

Another advantage of electroless nickel plating is that it is more cost-effective and efficient coating process than electroplating. It does not require electricity and less equipment are required to complete the process. There is no energy cost involved and less labor required for completing the process which makes this process highly efficient.

Gentle application

Electroless nickel plating can be applied with zero or little compressive stress ( https://www.sun-glo.com/blog/ ), making it gentle in application. It helps protect the integrity of the original product while making it durable and resistant to corrosion.

These are the five key advantages of electroless nickel plating which makes it a preferred choice for metal finishing in the metal industry.

The Bottom Line

Metal finishing plays an important role in providing protection to metal parts from corrosion and abrasion. Therefore, it is necessary to choose the right metal finishing process, and when it comes to protecting metal parts in tough conditions, definitely, electroless nickel plating is the best in the business.
