Rhodium plating is a process where a thin layer of rhodium metal is deposited onto the surface of another metal, typically silver, white gold or platinum, through electroplating. Rhodium is a precious metal that is part of the platinum group metals, and it has a bright white color, high reflectivity, and excellent corrosion resistance.
Rhodium plating is commonly used in the jewelry industry to enhance the appearance of white gold and silver jewelry, which can become discolored or tarnished over time. The rhodium plating creates a bright, shiny surface that is resistant to tarnishing and wear, and can help protect the underlying metal from scratches and other forms of damage.
The thickness of the rhodium layer applied during the plating process can vary, and typically ranges from 0.5 to 3 microns. Rhodium plating is a relatively quick and affordable way to improve the appearance of jewelry, and can be easily removed or reapplied as needed.
