Abstract
A new method of coating diamond particles was proposed in this paper, that is, using the high temperature generated by the thermal explosion reaction to induce the sublimation of volatile substances in the raw material and then deposit them on the surface of diamond particles to form one coating. The thermal explosion reaction of Mo/Al/B2O3 system was selected as an example. Results showed the high temperature generated by the thermal explosion reaction may induce a certain amount of Al volatilization. Al was deposited on the surface of diamond particles and reacted with trace oxygen in the environment to form Al2O3. Thus, Al–Al2O3 composite was coated on the surface of diamond particles.
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.
