摘要

研究了石墨和钛在真空中高速电子束蒸发冷凝制备厚凝tic基材料的可行性。该研究确定了沉积态和退火态冷凝物的密度、孔隙率和显微硬度对基体温度的依赖性，温度为1000℃。力学性能随TiC凝聚物含碳量的变化分析表明，在碳浓度为12-14 wt %时，弯曲强度达到最大值，而显微硬度在18-20 wt %时达到峰值。

Structure and Mechanical Properties of Thick Vacuum TiC Condensates Obtained by Electron Beam Evaporation

This study investigates the feasibility of producing thick condensed TiC-based materials through high-rate electron-beam evaporation–condensation of graphite and titanium in vacuum. The research determines the dependences of density, porosity, and microhardness of both as-deposited and annealed condensates, subjected to a temperature of 1000°C, on the substrate temperature. The analysis of mechanical properties as a function of carbon content in TiC condensates demonstrates that the flexural strength reaches its maximum at a carbon concentration of 12–14 wt %, while microhardness peaks at 18–20 wt %.

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.
