electrodeposition
The application of direct current is used for deposition of a metallic coating onto a conductive substrate and is called electrochemical deposition. In this process, the wafer is dipped into a bath containing active metal ions, which are deposited as the ions are reduced due to the influence of electric current. This is a general concept under most forms of electrodeposition used for surface coating, plating, and modification of surface properties.
Key Features:
- Metal Coating Formation: Creates very smooth and uniform coatings of metals on objects that aid in their beauty and utility.
- Customizable Layers: Thickness and composition of metals can be controlled in an extremely accurate way by tilting electric parameters or manipulating the composition of the solution.
- Increased Surface Qualities: Improvements in general characteristics such as surface properties for corrosion resistance, electrical conductivity, and wear.
Electrodeposition is used in the electronics and automotive industries, including making jewelry. Examples of this include making corrosion-resistant coatings on automotive parts and depositing thin layers of gold onto electronic connectors for improved conductivity. The process is thus perceived to be flexible and economically viable because of the various coatings that can be given different decorative, protective, and functional properties.
