| Abstract | Detonation gun-sprayed coatings are known for their high density, high bond strength, moderate substrate heating, superior surface finish, better wear/corrosion resistance, and low cost. In this study, detonation gun-spraying technique was used to deposit Ni-20Cr coating on a commonly used boiler steel ASTM A213 TP347H. The specimens with and without coating were subjected to cyclic oxidation testing at an elevated temperature of 700 °C in actual boiler environment to ascertain the usefulness of the coating. The mass change technique was used to establish the kinetics of erosion-corrosion. XRD and SEM/EDS techniques were used to analyze the exposed samples. The uncoated sample suffered from erosion, and a significant mass loss was recorded. It was observed that overall mass loss was reduced by 83% and thickness loss by 53% after the application of the coating. The detonation gun-sprayed Ni-20 Cr coating was found to be suitable to impart erosion resistance to the given steel in the actual boiler environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
