Ferrite nickel plating brightener and preparation method thereof

Abstract

The invention relates to a ferrite nickel plating brightener and a preparation method thereof. The ferrite nickel plating brightener mainly comprises nickel sulfate, sodium hypophosphite, sodium tartrate, ammonium chloride, ammonium bifluoride, sodium dodecyl sulfate and saccharin. The ferrite nickel plating brightener has the characteristics that the plating solution is stable in structure, the coating is high in binding force, excellent in corrosion resistance and high in hardness, the use amount of the brightener is small, and the like.

Description

technical field [0001] The invention relates to a brightener for ferrite nickel plating and a preparation method thereof, belonging to the field of electrochemical surface protection. Background technique [0002] Since the industrialization of the electroless nickel plating process in the 20th century, it has become the focus of research and development in the field of magnetic material coating due to its good corrosion resistance, wear resistance, and uniform thickness. [0003] At present, when we often encounter electroplated ferrite parts, many brighteners have good performance when they are just opened, the quality of the plating solution is running normally, and the quality of the coating is stable, but after a period of use, the quality of the coating declines. No matter how you supplement, add, or adjust the plating solution, it can't reach a good state. This is because the formula of the brightener itself is improper and the components in the brightener are out of ...

[0003] At present, when we often encounter electroplated ferrite parts, many brighteners have good performance when they are just opened, the quality of the plating solution is running normally, and the quality of the coating is stable, but after a period of use, the quality of the coating declines. No matter how you supplement, add, or adjust the plating solution, it can't reach a good state. This is because the formula of the brightener itself is improper and the components in the brightener are out of balance. As we all know, various brighteners are made of various intermediates The relative ratio of each component is one of the most important parameters in the solution composed of the mutual coordination of the brightener. During the electroplating process, the various components of the brightener are not consumed at the same time. Due to synergistic effects and other factors, the consumption will be according to the formula design. Therefore, although the brightener is continuously consumed and supplemented during the electroplating process, the designed formula is not reasonable. After a period of time, some intermediate components in the plating tank will be seriously surplus. If the proportion is out of balance, organic pollution will be formed, and other components will appear insufficient. At this time, the brightener in the plating solution will appear out of proportion.
