In the acid galvanizing process, the bonding of the coating is affected by a number of factors, and it is critical to ensure good adhesion of the coating to the substrate. Factors affecting adhesion include surface preparation, bath composition and operating conditions.
What is the cause of blistering in alkaline galvanizing process? In addition to the unclean pre-treatment stated in the previous article, you can also investigate from the following 4 directions.
The tin plating additives used in the sulfate matte tin plating process have a direct impact on the quality of the plated layer, and the plated layer scratching is often related to the use and regulation of these additives. The type of additives, their concentration and their ratio in the plating solution will affect the final quality of the plated layer.
In acid tin plating process, the plating solution turbidity not only affects the product appearance, but also may bring quality problems. Don't worry, we will teach you a few tricks, so that your plating solution as clear as ever!
In the chromium plating process, the size of the current is one of the most important parameters in determining the quality of the plated layer. The size of the current affects the deposition rate, deposition uniformity, gloss, hardness and adhesion of the coating in many ways.
Hard chrome brighteners are primarily used to improve the quality of the plated layer and include a range of organic compounds such as sulfates, fluorides, chromates and different types of organic additives that can affect various aspects of the hard chrome plating process, including deposition rates:
