Abstract
The effect of boron oxide on the surface of grains from superhard materials on the performance characteristics of grinding tools is studied. The possibility of increasing the strength of cubic boron nitride (cBN) grains by their thermal treatment in air at a low temperature due to the filling of their defective space with a B2O3 film is shown. The results of tests show that the wheel containing cBN powder have higher wear resistance and lower specific grinding energy. It is demonstrated that just boron oxide on the surface of grains from superhard materials is an important factor of increasing their performance characteristics in grinding tools.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
