What is eloctroplating?

Answer 1

Electroplating is a Platingprocess in which metal ions in a solution are moved by an electric field to coat an electrode. The process uses electrical Direct_currentto RedoxCationof a desired material from a solution and coat a Electrical_conductivityobject with a thin layer of the material, such as a metal. Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g., Abrasion_(mechanical) and wear resistance, Corrosionprotection, Lubrication, aesthetic qualities, etc.) to a surface that otherwise lacks that property. Another application uses electroplating to build up thickness on undersized parts.
