`Find low-cost tech to tackle corrosion'

Our Bureau

Visakhapatnam , Sept. 20

CORROSION control calls for a massive, co-ordinated effort by the research institutions and the user industries in the country with careful evaluation of the costs involved, according to Dr V.N. Rajasekharan Pillai, Vice-Chairman of the University Grants Commission.

He was speaking at the inaugural of the three-day twelfth national seminar on corrosion control. It was organised by the National Corrosion Council of India and the Central Electrochemical Research Institute(CECRI), Karaikudi.

Dr Pillai said that corrosion was in fact a global problem and the damage due to corrosion was quite enormous. At the same time, corrosion control methods and technologies were too expensive. "We have to strike a balance and discover innovative and inexpensive technologies to tackle the problem, which is easier said than done,'' he observed.

Dr A. Rajendran, Deputy Director, CECRI, said that in the US it had been estimated that the annual losses due to corrosion amounted to $276 billion. "Corrosion is like cancer. It eats into the economy,'' he said.

Dr N. Palaniswamy, Deputy Director, CECRI, said that India was losing an estimated Rs 50,000 crore per annum due to corrosion. Mr K. Ratna Kishore, Chairman of Visakhapatnam Port Trust, said they were spending Rs 8-12 crore per annum on corrosion control. "There has to be corrosion audit in all industries,'' he said.

Mr K.K. Rao, Director (Operations), Visakhapatnam Steel Plant, said that steel industry was particularly vulnerable to the problem and cost-effective technologies would have to be found out.
