This depends on the field of use. When it comes to decorative corrosion protection, attractive and perfect finishes as well as targeted design effects can be created with electroplating processes and coating systems involving copper/nickel/chromium. The automotive industry attaches great importance to long-term corrosion protection and attractive finishes, features which must also be able to withstand high temperatures. Cathodic corrosion protection fulfills these criteria. These finishes are achieved with galvanically deposited zinc and zinc alloys. Permanent protection against wear and corrosion can also be achieved with hard chrome plating.
