Special Issue Information

Dear Colleagues,

Design and development of advanced materials for high-performance applications and bringing these materials into use are the most challenging tasks of modern material engineering. The combination of two or more different materials offers a range of advantages. Metal–ceramic composites are natural candidates for these demanding applications due to the diverse and dissimilar physical properties of metals and ceramics, which gives the final products attractive mechanical, electrical, thermal, and biochemical properties and property combinations.

Combining dissimilar materials for these new applications creates interfaces whose properties and processing need to be understood to bridge the gap between the composite material microstructure and its final properties. In addition, the development of metal–ceramic composites becomes a major challenge due to the complexity of manufacturing processes.

In this Special Issue of Materials on “Novel Metal–Ceramic Composites” we are soliciting original experimental and theoretical papers, as well as comprehensive reviews which are focused on a novel scientific and technological progress associated with the preparation of nano- and microsized metal–ceramic composites. The scope of this Special Issue covers a very broad range of topics from fundamental concepts, experimental and theoretical studies relating to this type of composites, influence of constituent materials concentration, and geometric parameters of composite medium, determining the physicochemical properties, investigation of the microstructure and microstructure–property relationships, manipulation of properties through various manufacturing and processing techniques, metal–ceramic joining, modeling, and simulations. 

It is my pleasure to invite you to submit an original manuscript with your novel research results in this subject to Special Issue. Full papers, short communications, and reviews are welcome.

This article considers issues pertinent to the research of the phase composition, structure and mechanical properties of materials obtained from powders of composite (Ni-Ti)-TiB2, which have prospective applications in aerospace and automotive industry and engine construction. The starting powder materials (Ni-Ti)-TiB2 were obtained by self-propagating high-temperature synthesis (SHS). Research samples were produced using high-temperature vacuum sintering. It was shown that the use of such materials increases the wettability of the particles and allows the production of composites, the density of which is 95% of the theoretical one. Average particle size was 1.54 µm, average microhardness was 8 GPa, which is an order of magnitude higher than the average microhardness of pure nickel-based and titanium-based alloys, and the ultimate strength values were comparable to those of tungsten-based heavy alloys.

In this study, we successfully obtained Al-TiB2 composite materials using self-propagating high-temperature synthesis and preliminary mechanical activation of the initial Al-(Ti + 2B) powder mixture with a high aluminum content (70 wt.%). We investigated the possibility of controlling the structure of synthesis products, in particular, the size and shape of ceramic particles. We examined the effects of the mechanical activation of the initial powder mixture on the structure and particle size of titanium diboride in the synthesis products. We proposed a mechanism of structure formation in the synthesis products obtained by SHS using the method of preliminary mechanical activation of the initial mixture. We found that mechanical activation for 60-180 s led to the formation of isolated TiB2 particles of prolate and irregular shape. The average particle size of TiB2 in the synthesis products was 0.77 (after 60 s of mechanical activation) and 1.5 µm (after 180 s of mechanical activation), respectively. An increase in the duration of mechanical activation to 900 s led to the formation of an island (skeletal) structure, in which there were interconnected aggregates and isolated particles of titanium diboride. The average size of these particles was 4.3 µm. Full article

The preparation of metal–ceramic layered composites remains a challenge due to the incompatibilities of the materials at the high temperatures of the co-firing process. For densification, the ceramic thick-film materials must be subjected to high-temperature annealing (usually above 900 °C), which can increase the production costs and limit the use of substrate or co-sintering materials with a low oxidation resistance and a low melting point, such as metals. To overcome these problems, the feasibility of preparing dense, defect-free, metal–ceramic multilayers with a room-temperature-based method should be investigated. In this study, we have shown that the preparation of ceramic–metal Al2O3/Al/Al2O3/Gd multilayers using aerosol deposition (AD) is feasible and represents a simple, reliable and cost-effective approach to substrate functionalisation and protection. Scanning electron microscopy of the multilayers showed that all the layers have a dense, defect-free microstructure and good intra-layer connectivity. The top Al2O3 dielectric layer provides excellent electrical resistance (i.e., 7.7 × 1012 Ω∙m), which is required for reliable electric field applications. Full article
