In the current condition of high environmental protection requirements, traditional Cr(VI) passivators are gradually being eliminated from the market due to their toxicity and pollution.
In the plating process using hard chrome additives, localized non-plating is a common problem. This not only affects the aesthetics and uniformity of the plating layer, but also may lead to a decline in product performance and failure to meet the requirements of use. So, why does hard chrome plating have localized non-plating?
A plating manufacturer in the use of barrel nickel plating brightener, faced with barrel nickel plating workpiece recesses can not be plated, thin plating layer and easy to rust the problem. In the production process, the manufacturer found that it was difficult to achieve the ideal thickness of plating in the recesses of the workpiece after nickel plating, resulting in the workpiece rusting quickly, which seriously affected the quality of the product and production efficiency.
In the electroplating process, degreasing is a crucial step that directly affects the quality of the subsequent plated layer. In this article, we will discuss how to check the degreasing quality of parts after using steel electrolytic degreasing powder.
During steel processing, transportation and storage, the surfaces of steel parts are often contaminated with a variety of oils. These oils not only affect the appearance of steel parts, but also may have a negative impact on subsequent processing and use. Therefore, it is important to understand the types of oil and grease on the surface of steel parts and which steel chemical degreasing powder to use.
In the plating process, zinc-nickel alloy is favored for its good corrosion resistance and mechanical properties. However, in order to ensure the quality of the plating layer, the pretreatment process of the workpiece, especially the oil and rust removal, is particularly important. In this article, we will discuss in detail the key points that need to be paid attention to when using zinc-nickel alloy additives, such as the workpiece oil removal and rust removal pre-treatment process.
