摘要

摘要研究了石墨烯含量对 Al2O3 纳米复合陶瓷机械性能和摩擦学性能的影响。样品是在 1550°C 的固态下通过等离子火花烧结获得的。在室温、无润滑的情况下，按照球-盘方案对不含石墨烯和石墨烯含量为 2 wt % 的烧结样品进行了摩擦试验。结果表明，石墨烯降低了摩擦系数和磨损。还构建了微硬度与石墨烯含量的关系。石墨烯含量为 1%的样品具有最高的显微硬度。

Effect of Graphene on Microhardness and Tribological Properties of Nanocomposite Ceramics

Abstract—The effect of mechanical and tribological properties of Al₂O₃ nanocomposite ceramics depending on the graphene content is studied. The samples are obtained using plasma-spark sintering in the solid state at a temperature of 1550°C. The friction of sintered samples without graphene and with a graphene content of 2 wt % is carried out according to the ball–disk scheme at room temperature without lubrication. It is shown that graphene reduces the coefficient of friction and wear. The dependence of microhardness on graphene content is constructed. The sample with a graphene content of 1% has the highest microhardness.

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
