| Abstract | To study the performance of pure aluminium (Al) oxide film produced by high-speed wire electrical discharge machining (WEDM-HS), some characterisation indices including phase composition, surface morphology characteristics, roughness, friction coefficient, oxide content and thickness of the 1060 Al oxide film are researched, respectively, through X-ray diffraction, energy dispersive X-ray spectroscopy, scanning electron microscope, confocal microscope, contourgraph and nanoindentation. The results show that the produced oxide film of 1060 Al is mainly composed of Al2O3 phase after the 1060 Al sample processed by WEDM-HS. With the pulse width of WEDM-HS is gradually decreasing, the Al2O3 content values in the oxide film are all more than 84% with slight change. The surface morphology of the oxide film is made up of honeycomb holes of microns size. Moreover, the ladder-like microstructures of square bracket are found for the first time at the inside wall from bottom to top of the microholes. With the decreasing of the pulse width, the thickness and the friction coefficient of the oxide film first decrease, then increase and finally tend to be stable. They both have certain relationships with the Al2O3 content of the oxide film. |

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.
