In the process of trivalent chromium black zinc passivation, often because of the poor impurity resistance of the working solution, the passivation film of the workpiece is not black enough or the corrosion resistance of the coating is poor, resulting in poor quality of the coating of the workpiece and low production efficiency.
Alkaline etching is a key step in the aluminum plating pretreatment process, but the pungent alkaline mist produced in the traditional alkaline etching process not only affects the workshop environment, but also may be hazardous to workers' health. In order to solve this problem, we need to use alkaline aluminum microetching agent BC-20.
Electrolytic degreasing in electroplating production is a pretreatment process that utilizes an electrolytic process to remove grease and organic contaminants from the surface of metal workpieces. Cleaning the metal surface prior to plating is critical, as oil and grease can hinder the uniform deposition of the plating layer and may lead to quality problems such as peeling and flaking of the plating layer. Therefore, Bigely Electrolytic Degreasing Powder BC-1108 is your first choice!
Some customers asked that in the production process of using zinc-nickel alloy colored passivator, the passivation film of the workpiece appeared black phenomenon, what is the cause of this?
Zinc-nickel alloys are commonly used as plating materials for corrosion protection applications, and their salt spray resistance is critical for many industrial uses. Especially in areas such as marine equipment and automotive brake calipers, the protective properties of zinc-nickel alloys have a direct impact on the service life and reliability of the equipment. So how can we improve the salt spray resistance of zinc-nickel alloy blue passivation processes?
In the electroless nickel plating process, the porosity of the plated layer has a crucial influence on the corrosion resistance of the plated parts. If the porosity is high, the corrosion resistance of the plated parts will be reduced, which in turn affects their service life.
