The hard chrome plating process is a widely used surface treatment technology, which is mainly used to improve the hardness, abrasion resistance and corrosion resistance of workpieces. However, in practice, yellow spots sometimes appear on the plated surface, which not only affects the appearance, but may also impair functional performance. In this article, we will delve into the causes of yellow spots during hard chrome plating and introduce how to solve this problem using Bigely hard chrome additive Cr-2.
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?
In the pyrophosphate copper electroplating process, the control of current density is critical because it directly affects the quality and morphology of the plated layer as well as the deposition rate. Too high or too low a current density can lead to problems with the plated layer, such as roughness, looseness, unevenness, and even defects such as cracks.
What are the characteristics of steel oil removal powder, we will talk about it today.
In the process of using zinc-nickel alloy natural color passivator, when there is a problem with the passivation film, such as blue passivation film, is this caused by the problem of passivator? Actually, it's not. Maybe it's the plating solution.
Zinc-nickel alloy plating is a widely used metal surface treatment process that deposits an alloy layer of zinc and nickel on a metal surface through an electrochemical reaction. This alloy layer not only combines the characteristics of both metals, nickel and zinc, but also shows good performance advantages, making zinc-nickel alloy plating especially favored in the industrial field.
