Development and Research of Cermets Based on the NiAl–Al2O3 System Modified with MgAl2O4 Nanoparticles and Y2O3 Microparticles
This article studies nickel-based metal-ceramic materials with the addition of nanoparticles of refractory compounds in order to improve their mechanical properties and wear resistance. It is shown that aluminum-magnesium spinel nanoparticles and yttrium oxide microparticles play a key role in strengthening of material and blocking grain growth during sintering, which improves the mechanical properties. Nanoparticles help reduce friction and wear. X-ray and microscopic analyses of the cermets based on the NiAl–Al2O3 system are performed. The influence of sintering on the quality of composites is considered. The mechanical and tribological properties of composites with the addition of yttrium oxide and aluminum-magnesium spinel are determined. The influence of the structure and composition on the wear and friction of composites at different temperatures is considered. The microstructure and composition of wear tracks are analyzed, showing the improvement in the characteristics of composites with the addition of nanoparticles of refractory compounds. The importance of adding nanoparticles to improve the properties of nickel-based metal-ceramic materials in high-temperature applications is shown.
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.
