Nickel electroplating is a common surface treatment process, widely used in the protection and decoration of various metal products. However, the nickel plating process often encounters the problem of plating peeling, which not only affects the appearance of the product, but also reduces its anti-corrosion properties. In order to have an in-depth understanding of this phenomenon, we will nickel plating peeling of the main reasons are summarized below:
Improper surface treatment of the substrate
Surface treatment of the substrate is the first step in the plating process. If the surface of the substrate is not thoroughly cleaned of grease, oxidized skin and other impurities, the bonding between the plated layer and the substrate will be greatly reduced. An optimized cleaning process can effectively improve the adhesion of the plated layer. In addition, whether the surface of the substrate is uniformly roughened or not is also an important factor affecting the bonding strength of the electroplated nickel layer.
Inadequate activation process
A suitable activation treatment enhances the bonding between the plated layer and the substrate. The surface of the piston rod needs to be properly activated before plating to ensure that the nickel layer adheres well to the substrate. Insufficient activation may cause the plating to peel off.
Plating solution composition and operating parameters
The composition and operating parameters of the plating solution have a direct influence on the quality of the plated layer. Bigely nickel plating brightener Ni-301 is widely used due to its own composition and excellent performance. The use of Ni-301 improves the gloss and adhesion of the plated layer, thus reducing the occurrence of peeling. In addition, Ni-301 has good stability and can maintain the performance of the plating solution for a longer period of time, thus guaranteeing the consistency of the plating process.
Conclusion
In summary, the reasons for the peeling failure of the plating layer in the nickel electroplating process mainly lie in the surface treatment of the substrate, the activation process, the composition of the plating solution and the control of the operating parameters. The use of good quality nickel plating brightener, such as Bigely Ni-301, can reduce the peeling phenomenon and improve the reliability and stability of the nickel electroplating process.
