In daily industrial production, decorative chrome plating is widely used in many fields such as automotive parts, home appliances and hardware tools due to its beautiful appearance, strong corrosion resistance and high hardness. However, in the process of using decorative chrome additives, the quality of the plating layer may be affected by a number of factors, resulting in a variety of defects in the plating layer, among which the scorching of the plating layer is a relatively common and influential problem. In this paper, we will focus on the problem of decorative chrome plating scorching, discuss its causes, analyze how to effectively solve this problem, and help practitioners to improve the quality of plating and ensure production efficiency.
Burning phenomenon is usually caused by high current density, electrolyte composition disorder or improper operation control. Faced with these problems, we can take the following steps to deal with them:
First, ensure that the current density is controlled within the appropriate range. High current density operation can lead to localized overheating of the plated surface, deterioration of the quality of the plated layer, and even scorching. We recommend that the composition of the electrolyte as well as the stirring process must be controlled to avoid localized overheating when using high current density operation.
Second, the ratio of components in the plating solution should be strictly monitored. Improper ratios of chemical components such as chromic anhydride and sulfuric acid in the plating solution can also increase the risk of scorching. Regularly testing and adjusting the content of each component in the plating solution to ensure that it is within the proper operating range is one of the most important measures to prevent scorching of the plated layer.
In addition, the use of good decorative chrome additives is an effective way to minimize burnishing of the plated layer. An example of this is Bigely decorative chrome additive Cr-8, which provides a wide range of brightness, denseness and hardness, as well as high current efficiency, allowing operation at higher current densities and fast deposition rates. These properties not only improve the overall quality of the coating, but also reduce the risk of burnishing.
