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.

超硬材料晶粒表面的氧化硼是提高磨削工具性能特性的一个可能因素

研究了超硬材料晶粒表面的氧化硼对磨削工具性能特征的影响。通过在空气中对立方氮化硼（cBN）晶粒进行低温热处理，用 B2O3 薄膜填充其缺陷空间，从而提高了其强度。试验结果表明，含有立方氮化硼粉末的砂轮具有更高的耐磨性和更低的磨削比能。这表明，超硬材料晶粒表面的氧化硼是提高其磨具性能的一个重要因素。

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.
