Abstract

The hydrogen ion concentration (pH) of the process fluid, in the environment of which the tool and the workpiece contact and the polarization of the fluid occurs during friction, affects the process of diamond abrasive processing of tool materials. When processing hard alloy with a diamond tool, fluids with a neutral pH of 7 should be used, while for grinding oxide ceramics, process fluids with an elevated pH value of 8–9 are recommended. The use of polarized, specifically ion-activated process fluids during the machining process with a diamond tool on porous and conductive oxide-carbide ceramics makes it possible to decelerate wheel wear and bring down specific grinding energy consumption by up to 2 times.

加工液氢指数对金刚石砂轮性能的影响

摘要加工液的氢离子浓度（pH 值）会影响金刚石磨料加工工具材料的过程，因为在加工过程中，工具和工件会接触到加工液，并且在摩擦过程中加工液会发生极化。在使用金刚石工具加工硬质合金时，应使用 pH 值为 7 的中性加工液，而在磨削氧化物陶瓷时，建议使用 pH 值为 8-9 的高pH 值加工液。在使用金刚石工具加工多孔和导电氧化物-碳化物陶瓷的过程中，使用极化的、特殊离子活化的加工液可以减缓砂轮磨损，并将特定的磨削能耗最多降低 2 倍。

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.
