Résumé : |
In the first part, we studied about the losses and damages due to corrosion. There are basically three areas where the impact of corrosion is significant. The first one is economic, which define the enormous material loss resulting from various type of corrosion damages. The second is safety and reliability of equipment and structure, which may lead to catastrophic consequences due to corrosion, resulting an incalculatable loss of life and money. For example, Guadalajara explosions took place on April 22, 1992, in the downtown district of Analco. Numerous gasoline explosions in the sewer system over four hours destroyed 8 kilometres of streets. Gante Street was the most damaged. Officially, by the Lloyd's of London accounting, 252 people were killed; nearly 500 injured and 15,000 were left homeless. The estimated monetary damage ranges between $300 million and $1 billion. Similarly the Silver Bridge in West Virginia collapsed due to pitting corrosion ki II ing 46 people on the bridge in December, 1967. The third area, which is also no lesser important, is depletion of limited material resources including wastage of energy, water, manpower etc. Though the development is fast enough in almost every sphere of I ife, including the designing of structure and process equipments but the complexity of corrosive environments is also keeping its pace parallel. The designers, engineers, chemists and technologists are therefore, facing an insurmountable problem. Evan a small improvement in the prevention of corrosion would lead to a significant gain to the nation. The corrosion losses would have been greater if during last couple of decade, the subject had not been given the considerable attention. The corrosion problem has well understood and taken up by structure and equipment manufacturers, research organisations, corrosion associations and other institutions. If we wish to mitigate the corrosion, we have to understand the root cause of corrosion. In this part, classification of corrosion process would be discussed. |
