In the copper-nickel-chromium plating process, bright acid copper plating plays an important role, and if the quality of the copper plating layer is not up to standard, it will often have a certain impact on the subsequent plating. Therefore, it is necessary to study the causes and solutions of streaks on bright acid copper plating. In this issue, we will first talk about the influence and removal of organic impurities and oil impurities.
Irregular biting or leakage of aluminum workpieces after micro-etching treatment, as well as the phenomenon of poor bonding after plating, are important problems that plague many plating masters. These problems directly affect the surface quality of the workpiece and plating effect, the reason is mainly due to the surface of the workpiece on the oil and oil film cleaning is not complete.
In the electroplating process, degreasing is of great importance as a key pretreatment process. However, many electroplating factories often have to face a troublesome problem when electrolytic degreasing: frequent smoke and irritating odor during operation. These phenomena not only bring health hazards to the operators, but also seriously affect the environmental quality of the workshop. In this article, we will discuss the causes and solutions of this problem in depth, and provide suitable improvement measures for electroplating plant owners.
Zinc-nickel alloy plating has been put into production applications in the field of electroplating production due to its good corrosion resistance, high wear resistance and other advantages. In order to ensure the quality of the plated layer, the zinc-nickel alloy plated product usually needs to be passivated, of which black passivation is a very important method. Bigely zinc-nickel alloy black passivator plays a major role in electroplating production in the following ways:
Electroless nickel plating is an important surface treatment technology. Unlike conventional electroplating processes, electroless nickel plating does not require an applied electric current and forms a homogeneous, compact nickel-phosphorus alloy layer on the surface of the workpiece through a chemical reduction reaction. The properties of this coating can vary depending on the phosphorus content, thus playing a crucial role in different industrial applications.
In the electroless nickel plating process, the hardness of the plated layer is an important assessment index, which is related to the electroless nickel plating products can be sustainably applied in industrial production, so what are the methods of plating layer hardness testing? This issue of the article we will introduce two methods.
