Effect of bath temperature on quality during nickel plating
The temperature of the plating solution has a great influence on the plating process, which will affect the stability of the plating solution and the quality of the plating layer, so it is necessary to control the temperature. Let me tell you that in the process of electroless nickel plating, the change in temperature affects the plating process. Impact.
Electroless platingnickelDuring the process, the speed of metal ion deposition is proportional to the temperature, that is, the higher the temperature of the electroless nickel plating solution, the faster its deposition rate, if the temperature of the electroless nickel plating solution is lower, then it is the slower the deposition rate.
But with this elevated electroless platingnickelIt is not advisable to use the temperature of the bath to accelerate the deposition rate, because the bath may decompose at a high temperature, which reduces the service time of the bath. Therefore, we need to clarify each chemical At which temperature of the nickel plating solution, the deposition effect is the best, and it does not affect the stability of the plating solution.
In addition to affecting the plating speed, temperature also affects the quality of the coating. The increase in temperature increases the plating speed, the phosphorus content in the coating decreases, the stress and porosity of the coating increase, and the corrosion resistance decreases.nickelIt is very important to control the temperature evenly during the process. It is best to maintain the working temperature of the solution within ±2 degrees Celsius. If the temperature fluctuates too much during the plating process, a flaky coating will occur, the quality of the coating is not good and the adhesion of the coating will be affected, so everyone Pay attention to temperature control during the process.
The above is what Yantai Kaishi Industrial Co., Ltd. shared today about the influence of electroless nickel plating solution temperature on plating speed and coating quality. Do you all understand?
