Tooling materials science| Zusammenfassung: | The purpose of the work, the results of which are reflected in this article, was to comparestatic strength with the geometric shape of the projection of the grains of standard high-strength diamonds and the nature of wear of their cutting edge.To achieve the goal, after drilling with diamond-impregnated bits, equipped with high-strength synthetic diamonds, the granite of the Korostyshivsky deposit of the X drillability category, using a Zeiss EVO 50 scanning electron microscope, a study of the nature of diamond wear was performedA study of the surface morphology of AST200 synthetic diamonds shows that the total number of high-strength grains with a regular hexagon and square projection is 95-96%. Wear of high-strength diamond crystals of the mentioned grain shape occurs as a result of microshaking of their tops by the mechanism of brittle fracture, as a result of which the grain acquires a rounded shape and a fragmentation surface of the conchoidal type.Key words: synthetic diamonds, shape similarity of grain projection, destruction, character of wear, drill bits. |
