The surface hardness of tablets
Journal of Pharmacy and Pharmacology, 1970 AbstractA pneumatic micro-indentation apparatus has been used to determine the hardness of tablets of aspirin at various points on their diameter. All the tablets were 13 mm diameter; the compaction pressure and the particle size of the initial material were varied.

Surface Topography of PVD Hard Coatings [PDF]
Coatings, 2021 The primary objective of this study was to investigate and compare the surface topography of hard coatings deposited by three different physical vapor deposition methods (PVD): low-voltage electron beam evaporation, unbalanced magnetron sputtering and cathodic arc evaporation. In these deposition systems, various ion etching techniques were applied for

Asymmetrical Barkhausen Noise of a Hard Milled Surface [PDF]
Materials, 2021 This study is focused on the asymmetrical Barkhausen noise emission of a hard milled surface during cyclic magnetisation. The Barkhausen noise is studied as a function of the magnetising voltage and the hard milled surface is compared with a surface after heat treatment.

Analysis of indentation size effect in copper and its alloys [PDF]
, 2013 For describing the indentation size effect (ISE), numerous models, which relate the load or hardness to the indent dimensions, have been proposed. Unfortunately, it is still difficult to associate the different parameters involved in such relationships ...
