Thermal Shock-Resistant Ceramic Composites Based on Zirconium Dioxide1

Structure and Properties of ZrO2–20%Al2O3 Ceramic Composites Obtained Using Additive Technologies

“…To date, the specialists at Tomsk State University (TSU), Siberia, Russia have developed an method of additive printing complex profile items based on the principles of Material Extrusion with a piston implementing the deposition of finely dispersed thermoplastic systems (i.e., technology compositions of powders and thermoplastic substances) [2,3,4,5]. The specialists from TSU created a 3D printer that can work with thermoplastic pastes (suspensions) that are based on ceramic powders.…”

“…The demand for ceramic materials depends primarily on the growth of end-user markets. However, technological innovations have continually improved the performance and efficiency, stimulating the extended use of advanced ceramics in key sectors of the Russian economy [2]. Many industrial applications of advanced ceramic materials depend on the technological availability of the fabrication of three-dimensional (3D) ceramic items that have the required geometry [3,4].…”

“…According to the general classification of additive technologies (EN ISO/ASTM 5291:2107 and ISO/ASTM 52900), there are two different categories of AM processes: (1) single-step processes (also called “direct” processes), in which parts are manufactured in one operation, wherein the main geometric shape and the main material properties of the required product are achieved simultaneously; and (2) multi-step processes (also called “indirect” processes), during which parts are produced in two or more operations. The first operation, in general, provides the main geometric shapes, and the next operation unites the part into the assumed basic material properties [1,2,3,4,5,6,7]. Most of the AM processes for creating ceramics are multistage (indirect) processes.…”

Simulation of the Dynamic Behaviour of the ZTA Composites Obtained by Additive Technologies

“…Functional ceramics composites represent a class of materials that exhibit characteristic properties, in addition to those inherent to ceramics, such as chemical and thermal stability. Functional ceramics composites usually exhibit one or more unique properties in the biologic, elastic, electric, magnetic, thermal or chemical regimes [1,2]. Among the most prominent type of functional ceramics are ZTA ceramic composites.…”

On the possibility to fabricate ceramics using fused deposition modeling

“…It is also known [4,5] that ceramic materials have such properties that make them competitive against some structural materials including high alloy steels, nonferrous metals, and hard alloys. An example to illustrate this can be the experience of applying ceramic materials to manufacture tools and machine components.…”
