The greatest enemy of all types of metal is rusting and corrosion. The corrosive effect of rust is very destructive. Reports from various institutes show that the cost
of losses in the United States alone on rusting is about $276 billion dollars each year and a global figure of about $1 trillion dollars. The industries affected by this
devastating effect of rusting includes Production and Manufacturing, Transportation, Government, Utilities and Infrastructure. A process known as zinc plating is frequently used to protect metals such as iron and steel against
the relentless forces of corrosion. Zinc plating involves the electrodeposition of a thin coating of zinc metal onto the surface of another metal object, known as a substrate. The zinc coating creates a physical barrier that prevents rust from reaching
the underlying metal surface. Zinc is chosen because of its innate ability to fight corrosion. In fact, zinc is often referred to as the corrosion-prevention workhorse.
While the use of zinc compounds began more than 2,500 yeras ago, the production of metallic zinc first occurred in India around the 15th century. Today, nearly one-third of all zinc metal is used for galvanization, which is the coating of a metal surface to protect against rusts. Zinc plating is the most commonly used method of galvanization.
