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.
The causes of yellow spots are complex and are usually related to factors such as the composition of the plating solution, current density, temperature and the use of additives. Accumulation of impurities in the plating solution, improper use of additives and poor temperature control are important causes of yellow spots on hard chrome plating. Excessive impurities can lead to changes in the conductivity of the plating solution, thus affecting the quality of the plated layer, while too high or too low a temperature can destroy the uniformity of the plated layer.
Conventional additives have an impact on the quality of the plated layer. Through experiments, it is found that appropriate catalysts can effectively improve the uniformity and adhesion of the plated layer, thus reducing the formation of yellow spots. Too much or too little current density will lead to problems in the plating layer, and it is recommended to maintain a stable current density during the plating process.
Bigely Technology's hard chrome additive Cr-2 has shown good performance in practical applications.The Cr-2 additive has been developed by a team of engineers to improve the quality of the plated layer and to avoid yellow spots. The additive ensures a uniform and smooth coating by optimizing the composition of the plating solution and controlling the current density and temperature. In addition, the Cr-2 additive improves the abrasion and corrosion resistance of the plated layer and extends the service life of the plated parts.
In summary, the reasons for the occurrence of yellow spots in the process of hard chromium plating are various, mainly involving the composition of the plating solution, hard chromium additives, current density, temperature control and so on. Therefore, we need to control the process parameters, use hard chromium additives, and maintain the plating solution.
