Corrosion Map of India

CSIR –CECRI, Karaikudi has sketched a ‘Corrosion Map of India’ based on the data collected over a period of 18 years from 1993-2011 throughout the length and breadth of the country.  The corrosion map is the corrosivity mapping of the atmospheric environments and corrosion rate of specific engineering metal exposed to the same environment. The chemical nature of the atmospheric environments change with the levels of the pollution and climate.  Based on the already collected data there is an indication that the corrosivity of metal is spot specific rather than region specific.
