When using hard chromium additives and analyzing CrO3 and Cr3+, in addition to paying attention to the calibration of ammonium ferrous sulfate before use, ensuring a large titration jump range, and controlling the heating time of ammonium persulfate, it is also necessary to pay attention to the fourth point.
High temperature nickel additive is applied to the process of plating a nickel sulfamate base layer on continuous plating, followed by pure tin plating. This additive allows the workpiece to pass the high temperature reflow test without discoloration of the plated surface. So how should this high temperature nickel additive be managed during the use of each component of the plating solution?
Why is there yellow-green precipitation in nickel plating solution? This is the problem that a lot of electroplating factory masters consult, in order to help you as soon as possible to troubleshoot this fault, we write an article today to provide some ideas to solve.
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 a commonly used surface treatment technique to improve the corrosion, wear and hardness of a base material by forming a nickel-phosphorus alloy coating on its surface. Maintaining the stability and activity of the electroless nickel plating solution is critical in this process. In this paper, we will discuss how to effectively maintain the electroless nickel plating solution in production.
Electroless nickel plating is a widely used surface treatment technology that provides materials with excellent corrosion resistance and good mechanical properties. However, the performance of the plated layer does not only depend on the nickel plating process itself, but the post-plating treatment process is also an indispensable part. In this paper, we will discuss the post-processing of electroless nickel plating, including passivation, dehydrogenation of the plated layer and heat treatment, and illustrate how electroless nickel concentrate Ni-809 improves the quality of the plated layer.
