What factors affect the speed of electroless nickel plating

Electroless platingnickelThe process is widely used in the metal products industry with its excellent metal surface treatment technology. The speed of electroless nickel plating has a great influence on the processing efficiency of products. So what factors will affect the speed of electroless nickel plating? Let's take a look.

1. Temperature. When the temperature of the bath is increased, the speed of nickel plating is accelerated, but the stability of the bath is reduced and the service life is shortened. At the same time, the volatilization rate of ammonia is accelerated, which is more irritating to operation, and the pH value of the bath drops rapidly, which needs to be adjusted frequently. .

2, Concentration. Alkaline platingnickelUnder the condition that the pH value of the solution is relatively stable, the electroless nickel plating rate is basically independent of the nickel ion concentration, but mainly depends on the concentration of hypophosphite. When the hypophosphite increases exponentially, the nickel plating rate also increases exponentially. Increase.

3, pH value. PlatingnickelThe speed increases with the increase of pH, but the pH should not be too high, otherwise the stability of the plating solution will be reduced.

4. Loading capacity. Similar to electroless copper plating, if the loading capacity is too large, the nickel plating speed will decrease rapidly. If the loading capacity is too low, the nickel plating speed will be too fast, and the stability of the nickel plating solution will decrease.

The above points are the main factors that affect the speed of electroless nickel plating summarized by the electroless nickel plating factory. I hope that users will pay more attention in post-processing.
