Abstract | Nanostructured WC-17wt%Co coatings were deposited using air plasma spraying (APS) and high velocity oxy-fuel (HVOF) spraying techniques. While air plasma sprayed coatings were deposited as a function of critical plasma spray parameter (CPSP) with nitrogen as the primary plasma gas, HVOF sprayed coatings were obtained with propane as the fuel gas for different oxygen to fuel ratios. Microstructural characteristics and wear performance were evaluated for the deposited coatings with the aim to correlate microstructural and tribological characteristics of coatings. Effect of CPSP on wear performance of nanostructured coatings deposited using APS was seen to be much more significant as compared to the effect of oxygen to fuel ratio for corresponding HVOF sprayed coatings. The effect of normal load on weight loss in wear tests for nanostructured coatings deposited using APS was seen to be more prominent than that for corresponding HVOF sprayed coatings. Tungsten was found to be the dominant phase in nanostructured coatings deposited using APS, while WC is the dominant phase in corresponding HVOF sprayed coatings. Further, wear resistance of nanostructured WC-Co coatings deposited using APS was found to much smaller than that for corresponding HVOF coatings, particularly at higher contact pressures. |

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.
