Nickel plating refers to a layer of nickel on base materials for either durability or decorative purposes. On industrial parts, nickel plating acts as a shield to provide wear and corrosion resistance. Without any plating, machinery is susceptible to damage, which shortens its durability and increases repair costs. Different methods of nickel plating alter the end…
