“…Compared with the other methods, the arc discharge technique has the advantages of not being too expensive, simplicity, and being able to produce large quantities of CNTs. However, this method requires a large number of purification stages and the self-alignment of CNTs cannot be controlled, which leads to short CNTs with random sizes and directions [4,46]. The first growth of SWCNTs using the PLD method (Figure 8b) dates back to 1995 at Rice University, where a remarkable amount of pure SWCNTs about 5-20 µm in length and from 1 to 2 nm in diameter were synthesized.…”

“…CMCs also allow for improving the mechanical behavior of conventional polycrystalline ceramics, which typically suffer from high brittleness and low fracture toughness. In general, CMCs are produced from at least one micro-/nano-sized reinforcing/toughening phase embedded in a ceramic matrix [4]. The second phase can be constituted by ceramic micro-or nanoparticles (SiC and Si 3 N 4 ), nanotubes (e.g., CNTs), nanoplatelets (graphene), or hybrids of these materials.…”

This review outlines the state of the art, processing techniques, and mechanical testing methods of zirconia (ZrO2)-based composites reinforced by carbon nanotubes (CNTs). The use of CNTs as a secondary phase in a zirconia matrix is motivated by their outstanding crack self-healing ability, the possibility to tailor the desired nano-structural properties, and their exceptional wear behavior. Therefore, a detailed investigation into CNT features has been provided. The debate of using the different Vickers indentation fracture toughness equations to estimate the resistance of crack propagation was critically reviewed according to crack characteristics. Finally, this review particularly highlights the exceptional role of ZrO2-based composites as a promising material owing to their outstanding tribo-mechanical properties.

Summary Vacuum insulation panels (VIP) are usually manufactured using standardized manufacturing processes based on empirical values and in most cases with any fumed silica as the main component of the core material. However, not all applications have the same requirements in terms of thermal conductivity and service life. Therefore, it is useful to adapt the kind of core materials and their product specifications, such as particle size and porosity, to the different applications. Furthermore, in some applications cheaper core materials, like precipitated silica, would be a reasonable alternative. To replace the time‐consuming series of measurements for this purpose, this work offers comprehensive parameter studies to determine the optimum product properties of precipitated silica, fumed silica, silica gel, and glass spheres for use in the building sector, in transport boxes, as a superinsulation at atmospheric pressure, and as a switchable VIP. As a result, not only the preferred materials but also their porosities and particle sizes are presented. For atmospheric pressure and construction applications, fumed silica has to be preferred. For the transport sector and switchable VIPs as well as certain special applications, precipitated silica and silica gel may well be reasonable alternatives.

“…To achieve the desired properties in machining applications, the selection of the reinforcing agent, along with its morphology or orientation, is an extremely crucial parameter. Reinforcements could be utilized in the form of particulate, laminates, fibers, and whiskers [ 10 ]. Additives, especially carbon (C) and nitrogen (N), have a significant influence on Ti(C,N)-based cermets.…”

Development of high-performance cutting tool materials is one of the critical parameters enhancing the surface finishing of high-speed machined products. Ti(C,N)-based cermets reinforced with and without different contents of silicon nitride were designed and evaluated to satisfy the requirements. In fact, the effect of silicon nitride addition to Ti(C,N)-based cermet remains unclear. The purpose of this study is to investigate the influence of Si3N4 additive on microstructure, mechanical properties, and thermal stability of Ti(C,N)-based cermet cutting tools. In the present work, α-Si3N4 “grade SN-E10” was utilized with various fractions up to 6 wt.% in the designed cermets. A two-step reactive sintering process under vacuum was carried out for the green compact of Ti(C,N)-based cermet samples. The samples with 4 wt.% Si3N4 have an apparent solid density of about 6.75 g/cm3 (relative density of about 98 %); however, the cermet samples with 2 wt.% Si3N4 exhibit a superior fracture toughness of 10.82 MPa.m1/2 and a traverse rupture strength of 1425.8 MPa. With an increase in the contents of Si3N4, the Vickers hardness and fracture toughness of Ti(C,N)-based cermets have an inverse behavior trend. The influence of Si3N4 addition on thermal stability is clarified to better understand the relationship between thermal stability and mechanical properties of Ti(C,N)-based cermets.
