Corrosion & Material Protection Division (CMPD) is one among the major divisions in CSIR - CECRI has a very large and active multidisciplinary group of scientists working on various aspects of corrosion and its control. R&D in corrosion has been identified as a thrust area by Council of Scientific and Industrial Research (CSIR). CECRI as the lead laboratory, investigations in this vital area have led to the development of a number of Anti-Corrosion Products and Processes. This CMPD division is mainly concentrated R&D activities in three major areas such as Corrosion Control in Concrete Structures, Cathodic protection of buried and marine structures, and microbial corrosion.
CMPD as the pioneering division with enormous expertise has taken up first time in India did instrumentation for corrosion monitoring and structural health of Bridges and Structures at different locations of our country. In addition, instrumentation has also been done on different nuclear reactors in order to assess the life and safety with respect to corrosion of these reactors. Corrosion resistance concrete has been developed using different anodic and cathodic inhibitors. Extensive R&D work has been carriedout for utilization of waste products such as fly ash, rice husk ash, clay, matacolin etc, in concrete construction. Anti corrosive coating system such as inhibitive cement slurry coating and cement polymer composite coating have been developed for corrosion protection of reinforcement bars embedded in concrete structures. First time in India generating data on corrosion behaviour of pre-stressing steel embedded in high strength concrete is in progress. Corrosion monitoring sensors have in embedded in Bridges and Structures in order to predict the remaining service life of these valuable concrete structures.
Another important area of research in CPD is cathodic protection of buried and marine steel structures. Various alloys have been developed as anode materials for sacrificial protection system. Designing and development of techniques for CP systems has been done for various agencies like IOCL, NTPC, etc,. Test services like soil resistivity measurements, bacterial analysis, potential measurements, anode efficiency, cathodic disbondment tests on coatings, detection of flaw in pipelines etc,. have been carried out for various agencies under consultancy / sponsored basis.
CMPD has been carried out extensive studies on “updating corrosion map of India” and so far collected useful and first hand informative data from 37 exposure stations located in different parts of our country particularly along the coastal belts. Some industrial locations have also been included for collection additional data. The corrosion data collected based on exposure of different materials such as iron, zinc, aluminium etc, in various exposures stations have clearly indicated that the environmental pollution has a marked adverse influence on the durability of materials. In addition, CMPD has also carryout corrosion auditing in Indian industries to minimize the cost of corrosion.
In a country which has a large industrial base and many miles of seashore, it is important that a corrosion center be available to provide the research and education necessary to solve practical corrosion problems.
To provide consulting and testing services for industries
To conduct applied research
To develop new corrosion detection and control technologies
To investigate, evaluate, and determine materials performance and degradation in different environments in support to other government organizations, industry, and educational institutions
To participate in educational outreach activities
Corrosion science and technology are key to the development of new materials and innovative production processes for use in industries driven by the need to improve their capital productivity, operational reliability, efficiency, performance and health and safety of the world's physical assets. Corrosion remains a significant threat to the reliability and sustainability of materials, with costs of around 4% GNP which is several crores of rupees.
The Division has been conducting research and providing expert consultancy services to industry for several years. The Division consists of a diversified group of engineers and scientists who are available to provide a multi disciplinary approach to solving corrosion related problems.The services provided by CTE Division are varied and regularly attract national and international companies. CTE actively develops research projects in collaboration with private and state organisations that deliver practical outcomes for industry as well as contributing to the fundamental knowledge of the academic community.
