Abstract
A TiC coating was rapidly formed on the surface of diamond particles by thermal explosion reaction using Ti/Carbon black/PTFE/Diamond powders as raw material. XRD and SEM were used to analyze and observe the phase composition and microstructure of the coating. Results show that the phase composition of bonders was TiC, Ti, and TiF3 after thermal explosion reaction. The diamond surface obtained after the reaction can achieve good coating. Changing the diamond content in the raw material can regulate the phase composition of the coating. The coating on the diamond surface was mainly composed of TiC. When the diamond content in the raw materials was 20–40%, the coating was composed of TiC and TiF3. When the diamond content in the raw material was 60–80%, the coating was composed of TiC and Ti.
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.
