Abstract
New data on the wetting of superhard materials based on dense BN polymorphs with braze alloy metallic Zr–Ti–Ni, Ti–Zr–Cu–Ni, and Cu–Sn–Ti melts by the sessile drop method within a temperature range of 900–1000°C were reported. Contact angles were varied from 5° to 25° depending on the active component (Zr, Ti) in the composition of a soler. The metallic melt/BN contact interface was studied. The formation of Zr and Ti nitrides and borides at this interface was established. The soldered joints of cBN specimens with each other were manufactured, and the physicomechanical characteristics of soldered joints under shear and bending were studied.
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.
