In the electroplating industry, electroless nickel plated workpieces are favored for their good corrosion and abrasion resistance and uniform plating quality. However, when the thickness of the plating layer is only 2-3 microns, it becomes a challenge to pass the harsh 24-hour salt spray test. For this reason, Bigely Technology has developed a suitable electroless nickel plating solution and an oil-based sealer to solve this problem.
The renewal frequency of electroplating colored zinc passivation solution is not fixed, it is affected by a number of factors. The following are some of the key factors that affect the renewal frequency of electroplating colored zinc passivation solution:
In the electroplating industry, the appearance of white fog streaks on the surface of the tin layer is a common and troublesome problem. This defect not only affects the aesthetics of the coating, but also may adversely affect the performance of the coating, such as reducing corrosion resistance and weldability. As a research and development engineer of tin plating brightener, I will explore in depth the causes of white fog striations after tin plating, and explain why the choice of tin plating brightener Sn-807 can effectively solve this problem.
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.
Electroless nickel plating is a process of depositing a layer of nickel-phosphorus alloy on a metal surface through a chemical reaction. This alloy layer has good structure and performance, of which the hardness is one of the important indexes to measure the quality of the layer. As a R&D and sales engineer of electroless nickel concentrates, I know that the effect of plating temperature on the hardness of electroless nickel plating layer is very important.
Plastic plating process as a more mature process, people for the plating quality requirements are higher and higher, but for a variety of reasons, the plating plant in the production process will encounter some plating faults, such as pitting. So what are the causes of pitting? What is the relationship with the performance of alkaline electroless nickel plating additives?
