Electroplating passes an electric current through a bath containing dissolved metal ions, depositing a thin, adherent layer of that metal onto a conductive object serving as the circuit's cathode, used to protect a base metal from corrosion, improve its appearance, or build up a precise dimension. Luigi Brugnatelli demonstrated an early laboratory version in 1805, but the process only became a practical commercial technology after George and Henry Elkington patented electroplating with gold and silver in Britain in 1840.
Facts
Core PrincipleUse an electric current to move metal ions out of a solution and onto a conductive object, building a thin, controlled, adherent metal coating one layer at a time. 1 Cross-Tradition Connections
