The Process of cadmium copper
The process of cadmium copper involves the use of an electroplating technique to deposit a thin layer of cadmium metal onto a copper substrate. This process is used to protect the copper from corrosion and to enhance its electrical conductivity and solderability.The first step in the process is to prepare the substrate. The copper is cleaned and polished to remove any contaminants and to create a smooth surface for the cadmium layer to adhere to. The substrate is then immersed in a degreasing solution to remove any remaining oils or fats.
Once the substrate is prepared, it is placed into a bath of electrolyte solution that contains dissolved cadmium ions. When a direct current is applied to the bath, the cadmium ions are attracted to the negatively-charged copper substrate. As the ions deposit onto the surface, they form a thin layer of cadmium metal.
The thickness of the cadmium layer is controlled by adjusting the voltage and current of the electroplating process. A typical thickness for cadmium copper is between 0.5 and 15 microns.
After the cadmium layer is deposited, the substrate is rinsed with water to remove any excess electrolyte solution. The coated copper can then be further processed or used as-is, depending on the intended application.
Cadmium copper is used in a variety of industries, including electronics, aerospace, and automotive. Its corrosion resistance and electrical conductivity make it ideal for use in electronic components, while its solderability makes it a popular choice for manufacturing electrical contacts and connectors.
