Electroplating involves submerging metal surfaces in solutions with dissolved metal ions, through the electrical reduction effect to improve exterior appearance and corrosion resistance. Galvanizing is the coating of the base metal by applying a thick coat of zinc to produce a dull silver-gray finish.
