The roughness of the nickel plated layer is closely related to the nickel plating brightener used. Brightener is a chemical additive added to the plating solution, and its main function is to improve the gloss and flatness of the plated surface. The following points explain the effect of nickel plating brighteners on the roughness of the nickel plated layer:
1. Brightener type and quality: Different types of brighteners for nickel plating are suitable for different plating conditions and purposes. If the type of brightener selected is not suitable for the current plating system or plating requirements, or if the brightener is of poor quality, the uniformity and smoothness of the nickel layer may be affected due to insufficient or excessive chemical activity.
2. Brightener incompatibility: If the plating solution also contains other types of additives, these additives may be chemically conflicting or incompatible with the components of the brightener, affecting the quality of the plated surface. Bigely nickel plating brighteners are compatible with other brighteners.
3. Brightener decomposition products: During the plating process, brighteners may decompose and their products may not have a brightening effect, but instead can become impurities in the plating solution and increase the roughness of the plated layer.
4. Process parameters: Process parameters such as current density, temperature, and stirring speed all affect the performance of the brightener. If these parameters are not properly controlled, even if there is no problem with the brightener itself, it may lead to roughness in the plated layer.
To avoid the above problems, plating engineers or technicians need to carefully select Bigely nickel plating brighteners and conduct regular chemical analysis and replenishment of the plating solution to keep the brighteners at the right concentration and condition. Process parameters also need to be adjusted to ensure that the brightener is able to fulfill its role in helping to obtain a smooth and flawless nickel plating layer. If necessary, the bath can also be renewed periodically to remove accumulated decomposition products and impurities to ensure the quality of the nickel layer.
