SEM-based imaging and analysis of surface morphology of the Trizact™ advanced structured abrasives
Abstract
This paper shows that imaging and analysis of morphological features of the surface of modern structured abrasives in the pre-machining state can be carried out by means of electron microscopy supported by image processing and analysis techniques. The acquisition of SEM micrographs for active surfaces of the four (A6, A30, A65, A160 grades) monolayer abrasive discs 237AA (3M) with Trizact™ abrasive grains was carried out by the use of Quanta 200 Mark II (FEI Company) high-resolution scanning electron microscope. Visual analysis allowed for the observation of abrasive grains mainly in terms of the occurrence on their surface of various defects resulting from the technology of their production. For a parametric analysis, the authors used the Fiji 1.51s software (J. Schindelin et al.) which, in turn, made it possible to determine the values of the basic geometrical parameters characterizing the abrasive grains in the selected area of the active surface of assessed abrasive tool. The observation and measurement instruments used in the experimental studies described in this work and the proposed methodology may present an interesting alternative approach to the assessment of the surface morphology of advanced structured abrasives.

Since 2007 he has been a researcher in the Department of Production Engineering at the Koszalin University of Technology, where currently he works as an assistant professor. He has participated in 2 international and 3 national research projects, as well as presenting results from his work at 6 international and 28 national conferences. His research interests focus on problems concerning 2D-3D measurements of surface roughness using optical methods (especially those, which utilise light scattering phenomenon), various variants of the light and electron microscopy, machine vision systems, as well as image processing and analysis techniques. He has published more than 120 scientific papers in various international and national journals, book chapters and conference proceedings.
Mioriţa Ungureanu received her B.Sc. degree in Mechanical Engineering (specialization: Machines and Mining Installations) from Technical Univer-sity of Petroșani (Petroșani, Romania) in 1989, M.Sc. degree in Management and Business Administration (speciali-zation: Management) from Northern University Centre of Baia Mare (Baia Mare, Romania) in 2008 as well as Ph.D. degree in Engineering (specialization: Mechanics-Tribology) from North University of Baia Mare (Baia Mare, Romania) in 2004. Since 206 she has been a researcher in Department of Engineering and Technology Management at the North University Centre of Baia Mare, where currently she works as an assistant professor. Her current research interest are covered with selected issues from area of tribology (wear and friction of materials), non-destructing testing and metrology (measurements of surface roughness) as well as product innovation management. She published more than 50 scientific papers from those areas.
