| Abstract | Investigations of the microscopic properties of chemical vapor deposited diamond coatings on tungsten carbide tools are important to understand the coating–substrate interface (Uhlmann et al. in Prod Eng Res Dev 11(2):83–86, 2004; Surf Coat Technol 131, 395–399, 2000), the coating morphology, and the properties of cracks. Commonly the microscopic properties are analyzed in the transmission electron microscope (TEM). This paper presents a novel investigation method that includes a faster specimen preparation and that offers new analyzing possibilities. It applies a well-established device combining a scanning focused ion beam (FIB) column for the preparation of the specimens and a scanning electron microscope (SEM) for the analysis of the specimen. The aim of the paper is to verify preparation parameters for which the microscopic properties of the diamond coating are preserved during the FIB preparation and to show that the SEM analysis provides the same results of microstructure and element distribution compared to the TEM analysis. Furthermore, the feasibility of new analysis methods is studied. The FIB/SEM method traces and images defects in the nanometer range like cracks, crack propagation directions, delaminations, and layer inhomogeneities directly. The bulk FIB-prepared specimens are suitable for a precise standard-based element quantification and distribution analysis using energy or wavelength (WDX) dispersive X-ray spectroscopy. Moreover, the WDX analysis distinguishes between graphite-like carbon and diamond. |

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.
