Use of synthetic superhard material Elbora-B in rock-destroying drilling tools
Abstract
Successes in the synthesis of new superhard materials, in particular, cubic boron nitride (elboron), which has increased heat resistance compared to natural diamond and hard alloy (respectively 1.8 and 1.6 times) and chemical inertness to ferrous compounds, opened wide opportunities to expand and improve the raw material base for the manufacture of drilling rock-destroying tools ...
