Electroless nickel plating is widely used in various industrial fields, but pinholes often occur when the thickness of the plated layer is large, thus affecting the bonding and overall quality of the plated layer. In this issue, we will introduce how nickel plating wetting agent can improve the quality of electroless nickel plating layer and avoid the problem of pinhole plating.
A good potassium chloride galvanizing brightener is not only reflected in the bright uniform appearance, but also has a superior performance, and through the performance test can understand the brightener is good or bad. Take BZ-528 potassium chloride galvanizing brightener of Bigely Technology as an example for performance test:
The pH value of Bigely neutral tin plating process is nearly neutral, which is suitable for the plating of materials susceptible to acid, alkali influence or corrosion, such as special glass, ceramic materials as the substrate of the component solderable ends, leads. So, how should we maintain the plating solution in daily production?
For the surface treatment workshop, the qualified and stable composition of the plating bath is the prerequisite guarantee of the surface treatment quality of the workpiece. The quality of electroplating can be guaranteed by managing the hard chromium bath well. Liquid composition information is the basis of liquid management, which can be used to effectively maintain and adjust the liquid, so that the components of the liquid have been stable and meet the requirements, laying the foundation for the stable surface treatment quality of the workpiece. The information of tank composition is obtained by chemical analysis, which is often called tank analysis.
In the pre-treatment stage of the plating process, conventional pickling processes (hydrochloric acid, etc.) are usually used to remove oxidized layers and rust from the surface of the workpiece. However, this process can lead to hydrogen embrittlement of the plated layer, which significantly affects the mechanical properties and service life of the plated product. Hydrogen embrittlement is a phenomenon in which the ductility and toughness of a material are significantly reduced in the presence of hydrogen, leading to an increase in its brittleness and susceptibility to fracture during use.
In zinc-nickel alloy plating and passivation treatment, yellowing phenomenon often occurs at the corners and holes, which seriously affects the overall aesthetic and protective performance. In this regard, the application of Bigely Zn-323 zinc-nickel alloy trivalent chromium blue zinc passivator effectively solves these problems. Today's article will help you analyze the advantages of Zn-323 and its merits in practical applications.
