Alkaline zinc-nickel alloy plating is a widely used corrosion protection technology in industry, especially important in working conditions where high corrosion resistance is required. In this paper, we will discuss the effect of nickel content on corrosion resistance in this process and recommend the use of Bigely BZ-617 alkaline zinc-nickel alloy additive to improve the quality of the plated layer.
Plastic plating process occupies an important position in modern industrial production, especially the direct plating of ABS plastics, which can be plated with a beautiful and durable metal layer on the surface of the plastic by means of an appropriate pretreatment process. Colloidal palladium activator plays a crucial role in this process. However, plating factories often encounter the problem of high dosage and high cost of colloidal palladium activator. How to reduce the dosage and cost of colloidal palladium under the premise of guaranteeing the plating effect has become a technical challenge that needs to be solved nowadays.
Some customers inquired that in the production process of using black zinc passivator, the appearance of the workpiece passivation film is obviously black and shiny, but soon after drying, the passivation film will appear the phenomenon of small white spots, what is the reason for this?
In modern industry, trivalent chromium colored zinc passivation process is widely used in the electroplating processing industry for its good corrosion resistance and environmental advantages. However, in practice, iron impurities in the passivation solution often adversely affect the appearance and quality of the film layer. In order to ensure the stability of the passivation process, we need to gain a deeper understanding of how iron impurities affect the process and use suitable passivators to meet this challenge.
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?
