electroplating:
Electroplating is the process of covering a substrate with a thin layer of metal using electric current, mainly to improve corrosion resistance, appearance, or other surface properties.
Key Features:
- Electroplating Process Mechanism: The object-to-be-plated is kept immersed in the electrolyte solution containing metal ions, and an external electric current is passed through the solution, allowing the deposition of metal ions on the surface of the object.
- Common Metallic Coatings: Commonly used metals of electroplating include gold, silver, copper, nickel, and chromium.
- Applications: Used chiefly to beautify, to protect against corrosion, to improve wear resistance, and to enhance electrical conductivity.
Electroplating finds a great deal of applications in such industries as jewelry, where it provides a decorative aspect; automobile, where chrome plating adds to both appearance and functionality of the component; electronics, where electroplating enhances conductivity of components; and aerospace, where protecting metal parts from corrosion is a major concern. The advancement in electroplating techniques continues to enhance efficiency of the process, its environmental impact, and scope of materials that can be coated, rendering this versatile production method indispensable in present-day manufacture.
