The trivalent chromium black zinc passivation process has become a popular choice for galvanizing treatments in recent years due to its environmental credentials and low toxicity. However, despite its good corrosion resistance, it performs relatively poorly in terms of wear resistance. The causes of this phenomenon are mainly related to the physical properties, chemical structure and process control of the passivation film.
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?
When methanesulfonic acid tin plating additive is used, the acidity of the plating solution is relatively low, and the corrosion is relatively small. In the use of methylsulfonic acid tin plating additives, we can understand the advantages and disadvantages of additives through performance tests. The following takes the methylsulfonic acid tin plating additive Sn-819 from Bigely Technology as an example to conduct a performance test:
Matte tin plating is a widely used electroplating process used to deposit a uniform layer of tin on metal surfaces to provide corrosion protection, increase solderability and enhance appearance. This tin layer has a certain "matte" or "non-glossy" effect, as opposed to shiny tin plating, and is characterized by the following:
The high-temperature nickel plating process is an industrial surface treatment technology that involves depositing a nickel coating on the surface of a metal or other material. The main purpose of this treatment technique is to improve the corrosion resistance, abrasion resistance, and high temperature resistance of the material, as well as to improve its surface finish. Below are a few important roles and application areas of the electroplated high temperature nickel process:
Some customers ask why the pre-treatment step of degreasing should be added before tin plating of cold rolled steel plates? And how to choose the right steel electrolytic degreasing powder?
