When we use nickel sulfamate additive in the production process, sometimes the brittleness of the nickel coating is large, which affects the performance and quality of the coating.What causes the brittleness of nickel sulfamate coating?
In the production process of using nickel sulfamate additives, sometimes although the stress of the coating is high, it can still meet the requirements, but the heat resistance and corrosion resistance of the coating cannot meet the requirements.So how should we improve the corrosion resistance of the coating?
The semi-bright nickel process is to use semi-bright nickel plating additives in double-layer nickel or multi-layer nickel system electroplating to obtain semi-bright nickel bottom layers with high corrosion resistance requirements.In the production process, we must ensure that the potential difference between the semi-bright nickel layer and the bright nickel layer is 120~145mv, and it has good corrosion resistance.How to maintain the plating solution?
When we use semi-bright nickel plating additives for production, sometimes the composition of the plating solution and process parameters are within the normal range, but the deep plating ability of the plating layer is poor and there are pinholes. What should we do?
Some customers are asking, when using alkaline zinc-nickel alloy additives, in order to ensure the stability of nickel content in the coating, how to control the current density better?
We use high-sulfur nickel additives to obtain a very thin nickel punching layer between the bright nickel layer and the semi-bright nickel layer, which is far more active than the other two layers.When we plated high-sulfur nickel on the nickel-plated layer, but the potential difference between the nickel layers did not increase, what should we do?
