The Relationship between Corrosion Resistance and Coating Composition of Nickel Plated Copper Foil

With the rapid development of electronic technology, the demand for material corrosion resistance is also increasing. Nickel plated copper foil, as an important electronic material, has a wide range of applications in fields such as batteries, capacitors, and flexible circuit boards. The corrosion resistance of nickel plated copper foil is directly related to its service life and reliability. The purpose of this article is to explore the relationship between the corrosion resistance of nickel plated copper foil and the composition of the coating, with particular reference to Advanced Institute (Shenzhen) Technology Co., LtdCopper foil nickel platingResearch achievements in the field of technology.

Basic characteristics of nickel plated copper foil

Nickel plated copper foil is a layer of nickel metal coated on the surface of copper foil to improve its corrosion resistance, conductivity, and processability. Nickel is an excellent conductor with conductivity second only to copper and excellent corrosion resistance. By plating a layer of nickel on the surface of copper foil, it can effectively prevent copper oxidation and corrosion, and extend the service life of electronic components.

The influence of coating composition on the corrosion resistance of nickel plated copper foil

1. Nickel salt content

Nickel salt is one of the main components of nickel plating solution and has a significant impact on the quality of the coating. An appropriate amount of nickel salt can ensure the uniformity and density of the coating, thereby improving its corrosion resistance. Excessive or insufficient nickel salt content may lead to a decrease in coating quality, thereby affecting corrosion resistance.

2. Use of additives

Additives such as chelating agents, stabilizers, and surfactants are often added to nickel plating solutions to improve the performance of the coating. For example, additives such as glycine and sodium hypophosphite can improve the uniformity and density of the coating, thereby enhancing its corrosion resistance. In addition, some specific additives can also endow the coating with special properties, such as improving hardness, wear resistance, etc.

3. Coating thickness

The thickness of the coating has an impactNickel plated copper foilOne of the important factors affecting corrosion resistance. The thicker the coating, the stronger the protective effect on the substrate, and the better the corrosion resistance. However, excessively thick coatings may increase costs and affect the conductivity and processability of electronic components. Therefore, it is necessary to reasonably control the thickness of the coating while ensuring corrosion resistance.

4. Coating structure

The coating structure also has a significant impact on the corrosion resistance of nickel plated copper foil. For example, amorphous structured coatings usually have higher corrosion resistance because their surfaces do not have defects such as grain boundaries and dislocations, making them less prone to corrosion. In addition, the porosity and grain size in the coating can also affect its corrosion resistance.
