According to Confederation of Indian Industry-Corrosion Management Committee (CII-CMC), proper material selection in auto industry can increase fuel efficiency by 7 per cent. According to an official in CII-CMC, with every 10 per cent of weight eliminated from a vehicle’s total weight, fuel economy improves by 7 per cent. Corrosion in automotive leads to loss of material, leading to failure and breakdowns, dimensional inaccuracy, degradation of aesthetics, deterioration of mechanical properties and increase in maintenance cost.
It observed the estimated direct cost of corrosion across the world exceeds $2.2 trillion, which is about 3-4 per cent of the GDP of industrialised countries. Corrosion accounts to a loss of about Rs 80,000 crore per annum in India, of which automotive industry accounts for Rs 4,000 crore, according to a CII-CMC release. It is estimated 25-40 per cent of corrosion cost could be saved by implementing proper corrosion management practices.
