| Abstract | A new experimental capability for elevated temperature nanoscale friction measurement is described. Its stability and resolution were demonstrated in two case studies up to 750 °C. A stainless steel probe was used to study friction between steel and glass at 25, 200 and 400 °C. Friction forces were calibrated at temperature. The friction coefficient increased between 25 and 200 °C, but stick–slip was dominant at 400 °C due to chemical interaction between the stainless steel probe and the glass. This was verified by scanning Energy Dispersive X-ray Spectroscopy analysis. A WC–Co probe was used to study friction on a range of TiN-based and Cr$_{54}$Al$_{20}$C$_{26}$ (so named MAX-phase composition) coatings at 25, 400 and 750 °C. A maximum in friction coefficient was observed at 400 °C. The decrease in friction at 750 °C was associated with the formation of lubricating surface oxides and oxidation-associated surface roughening. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
