Some customers inquired that during the production process using semi-bright nickel additives, the bonding of the plating layer is poor, resulting in the semi-bright nickel plating layer coming off easily, what is the reason for this?
By using high sulfur nickel additives, we can obtain a very thin nickel rinse layer between the bright nickel layer and the semi-bright nickel layer, which is much more active than the other two layers. The potential difference between the high sulfur nickel layer and the bright nickel layer can be increased by at least 20mv, which improves the corrosion protection of the nickel layer. When we plated high sulfur nickel in the plating layer, but the potential difference of the nickel layer did not improve what to do?
Localized blistering of the plating is a common quality problem in the production of barrel nickel plating of iron parts, and the following are some of the common causes that may lead to such failures:
In the electroplating industry, the application of acid copper brightener is important, which directly affects the quality and performance of the plated layer. Acid copper brighteners contain a variety of organic compounds and additives that play an important role in the electrodeposition of copper.
Aluminum alloy workpiece must be immersed in transition metal plating, such as immersion zinc, tin, nickel metal, in order to obtain a good combination of plating, most of the current applications in mass production to sink zinc for more than the secondary zinc process is dominant, the sinking of zinc water is generally by the market, with each accounted for half of the market. The maintenance and management of the zinc precipitation agent need to pay attention to the following points:
Electroplating is a physico-chemical process that utilizes electrolysis to form a uniform, dense, and well-adhered coating on metals, alloys, or other conductive materials. During the plating process, the cleanliness of the surface of the workpiece is directly related to the quality of the plating. Especially, electroplating degreasing process is one of the key steps to ensure the quality of electroplating.
