Electro galvanization is a galvanization process in which a layer of zinc is bonded to steel in order to protect against corrosion. The process involves electroplating, running a current of electricity through a saline/zinc solution with a zinc anode and steel conductor. Zinc electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. Electroplating is primarily used to change the surface properties of an object (e.g. abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
Compared to hot dip galvanizing, electroplated zinc offers these significant advantages:
- Lower thickness deposits to achieve comparable performance
- Broader conversion coating availability for increased performance and color options
- Brighter, more aesthetically appealing, deposits
Electroplating is widely used in various industries for coating metal objects with a thin layer of a different metal. It provides the most effective and economical way to protect your parts against corrosion.
AUTOMOTIVE APPLICATIONS
One common industrial application of electroplating is in the automotive industry. Electroplating is frequently used to refurbish old chrome parts such as bumpers, grills and tire rims to make them look brand new. Electroplating on plastic is also used for chrome-plating the lightweight but sturdy parts that are a staple of the modern automobile.
CORROSION PROTECTION
The industrial use of electroplating is also a popular choice in businesses when corrosion against protection is necessary to prevent the premature demise of metal materials. Nickel plating, tin plating and their various alloys are all used for corrosion protection on nuts, bolts, housings, brackets and many other metal parts and components. Gold electroplating also provides superior corrosion and tarnish protection, although it is more expensive than other plating processes.
ELECTRICAL COMPONENTS
Industrial applications of electroplating include use on electrical parts and components. Silver electroplating, for example, is often used on copper or brass connectors due to its superior conductivity. Other precious metals such as gold and palladium plating are commonly used for switchgear in the telecommunications industry.
