Role of Phosphating systems in Electrodeposition priming & Latest Trends in Surface Coating in Automobile Industry

Iron and steel are so very widely used in Engineering Industry that any Country's progress can be judged from the consumption of this. Iron is mostly found as oxide
minerals in the nature from which by metallurgical processes we convert these oxides of iron into metallic iron and by alloying we make steel. Unfortunately natural process is such that this iron and steel due to atmos-pheric action again tries to go back to oxide state
which we call corrosion.
