Effect of Sintering Pressure on the Properties of PcBN Carbide Inserts
PcBN (polycrystalline cubic boron nitride) carbide insert were synthesized with cBN/Zr/Al as raw material under high temperature and pressure. The effects of synthesis pressure on the interfacial morphology, wear resistance, microhardness and flatness of PcBN carbide insert were investigated. The test results show that with the increase of synthesis pressure, the composite interfacial bond is more dense and homogeneous, and the bonding strength between the cBN layer and the alloy substrate is higher. Additionally, the density, microhardness and abrasion resistance of the PcBN carbide insert were improved. Meanwhile, under the ultra-high pressure, the thickness deviation of the PcBN carbide insert gradually decreases, the thickness distribution gradually becomes uniform, and the flatness of the samples gradually becomes better.
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.
