Reflection Electron Microscopy

It has been found that the abrasion of diamond-on-diamond depends on the crystal orientation. For a {100} face, the friction coefficient for sliding along <011> is much higher than that along <001>. For a {111} face, the abrasion along <11> is different from that in the reverse direction <>. To interpret these effects, a microcleavage mechanism was proposed in which the {100} and {111} surfaces were assumed to be composed of square-based pyramids and trigonal protrusions, respectively. Reflection electron microscopy (REM) has been applied to image the microstructures of these diamond surfaces.{111} surfaces of synthetic diamond:The synthetic diamonds used in this study were obtained from the De Beers Company. They are in the as-grown condition with grain sizes of 0.5-1 mm without chemical treatment or mechanical polishing. By selecting a strong reflected beam in the reflection high-energy electron diffraction (RHEED) pattern, the dark-field REM image of the surface is formed (Fig. 1).

The article is a rejoinder to the work of Yury S. Skubko, previously published in the Journal of the Institute for African Studies, on Moscow’s relations with De Beers. It is based not only on the available literature but also on the author’s personal experience. The author shows that under the monopoly of this South African company in the field of diamond sales, Soviet organizations, even in the conditions of a South African boycott, were forced to deal with its subordinate structures and the attempts to sideline them were in vain. In particular the article analyses the attitude to a controversial agreement signed by the Soviet state-owned “Glavalmalmazzoloto” and De Beers Centenary in 1990, when, like in many other cases in the “Gorbachev’s era” Moscow’s principle stand was eroded for short-term results even personal gains. The author comes to the conclusion that the responsibility for Moscow’s dealings with De Beers must be borne not by our country, but above all by the United Kingdom, which allowed De Beers have the headquarters of its Central Selling Organisation (CСO) in London.
