Electroless nickel plating is a commonly used surface treatment technique to improve the corrosion, wear and hardness of a base material by forming a nickel-phosphorus alloy coating on its surface. Maintaining the stability and activity of the electroless nickel plating solution is critical in this process. In this paper, we will discuss how to effectively maintain the electroless nickel plating solution in production.

The importance of maintaining electroless nickel plating solutions

1. Extend the service life of the solution

A well-maintained electroless nickel plating solution extends its useful life, thereby reducing production costs and wasted resources.

2. Ensure the quality of plating

Stabilized solution helps to maintain the uniformity and consistency of the plated layer and improve product quality.

3. Reduction of production risks

Production interruptions and equipment damage due to solution failure can be avoided by timely adjustment and maintenance of the solution.

Maintenance method of electroless nickel plating solution

1. Adjustment of pH

The pH of the electroless nickel plating solution has a great influence on the quality of the plating. Generally speaking, it is ideal to keep the pH between 4.6 and 5.0. The pH can be adjusted by adding ammonia and acetic acid.

2. Monitoring of nickel ion and reductant concentrations

Periodically measure the concentration of nickel ions and reducing agents (e.g., hypophosphates) and replenish as necessary. Too low a concentration of nickel ions can lead to thinning of the plating, while too much reducing agent may trigger decomposition of the solution.

3. Temperature control

Temperature has a significant effect on the reaction rate of electroless nickel plating. Normally the solution temperature should be kept between 85-91°C. Too low a temperature reduces the reaction rate, and too high a temperature may cause the solution to decompose. 

4. Filtration of impurities

Regular filtration of the solution removes metal particles and other impurities, preventing them from affecting the quality of the plating. The use of filter cloth and activated carbon are common methods of filtration.

5. Regular replenishment of additives

Electroless nickel plating solutions contain a variety of additives that are used to regulate the properties of the plated layer such as brightness, hardness, etc. These additives are gradually depleted over a long period of time. These additives are gradually consumed during long-term use and need to be replenished as required.
