On morphometric uniformity of diamond micron powders

The influence of physical-mechanical characteristics of AS6 synthetic diamond powders on wear resistance of grinding tools

“…Also, we analyzed the following morphometric characteristics of AS6 160/125 grains: area of grain projec tion, actual perimeter (p r ) and convex perimeter (p c ) of the grain contours, maximum and minimum Feret diameters (F min and F max ), mean diameter (d m ) and equivalent diameter (d eq ), form factor (C r ) of actual image of the grain projection, ellipticity (El), Feret elongation (F e ) and surface roughness of grains. A detailed description and geometrical interpretation of these and other morphometric characteristics as identified by DiaInspect.OSM system are provided in [21]. Given below are the mean values of the measured characteris tics (see Table 6) and indices of adequacy of these mean values by the stability criterion (Table 7).…”

“…The conceptual meaning of these characteristics is presented in the methodological materials of the manufacturer of the DiaInspect.OSM device [8] and in the publications of the authors of this article, for example, in [3,9].…”

“…As a result, smoother particles fall into the foam product, and rough particles into the chamber. The presence of iron ions of Mohr's salt in the pulp increases the selectivity of fatty acid action due to greater adsorption of iron ions on the rough surface of diamond particles, which contributes to the adsorption of polar dimers and fatty acid ions [2,3].…”

“…Our studies have shown that pulsed high-voltage electric discharge (HVED) treatment of grinding powders and micro-powders of diamond makes it possible to obtain powders that are more uniform in terms of morphometric characteristics [2]. To improve the quality of PSA, sorting by various methods is used, including flotation separation [3][4][5].…”

“…Morphometric characteristics (minimum (Fmin, μm) and maximum (Fmax, μm) Feret diameters, grain height (Н), grain projection roughness (Rg), Feret elongation Fel, average grain diameter (dm), convex image form factor Сr, was determined using the DiaInspect.OSM device [8]. The list and geometric interpretation of these characteristics, their conceptual meaning, are given in the descriptive and methodological materials of the manufacturing company for the DiaInspect.OSM device, in the original publications of its developers [8] and in the publications of the authors of this article [4,9]. The specified characteristics describe the size (Fmin, Fmax, dm) and shape (Сr,, Fel, of the grains.…”
