“…Most of them were received from recognized armour ceramic suppliers; however, some tested pressureless sintered carbide compositions have been prepared jointly with other organizations. RBSC and RBBC ceramics were also obtained from the recognized armour ceramic suppliers, and their technology is based on molten silicon infiltration of SiC or B 4 C preforms; biomorphic RBSC ceramics were processed via silicon infiltration of the wooden preforms carbonized by high-temperature pyrolysis [15]. Manufacturing of the developed heterogeneous SiC-based ceramics AS, ASN, ESS, ESAS was described earlier [14].…”

“…Their structures depend on not only the size and PSD of starting SiC or B 4 C powders, but also on the source of carbon (mostly, type of organic binders and feature of their pyrolysis) and applied technology. Biomorphic RBSC consisted of a lower content of SiC (mostly β‐SiC formed due to interaction of Si with C) and a significantly higher content of residual Si (about 30 vol.% based on calculation) with a very small amount (up to 3 vol.%) of carbon 109 . Their structure (Figure 17C) is more homogeneous than “conventional” RBSC that is defined by the used wooden preform.…”

“…In this case, hard carbide or some other ceramic phases are bonded by in situ formed SiC or by the metallic phase. Biomorphic RBSC can be produced when the pyrolyzed wooded preforms are infiltrated with molten silicon yielding SiC formation 107–110 . Different shapes can be manufactured using this approach, although the difficulty to infiltrate components with thick walls (>15–20 mm) or uneven thicknesses limit this process applicability.…”

The applications of advanced ceramics, composites and coatings in mineral, mining, fuel production, and processing are reviewed. The materials include oxide and non‐oxide ceramics (specifically SiC‐based), ceramic–ceramic, and ceramic–metal composites, coatings on metallic components where functional application properties can be achieved. Some principles of materials selection, specifically for erosion wear and corrosion applications, and manufacturing are considered. The examples of the successful development and processing of ceramics, coatings, and composites with manageable structures and phase compositions, in the erosion‐related applications, particularly conducted by the author, are discussed and reviewed. Specifically, industrially employed types of ceramics and processing routes were focused on the considered applications. Particular demands for advanced materials with high reliability and complex shapes or for protective coatings on complex shape steel components and long tubing with inner surface protection require novel and optimized processing. The factors affecting erosion and erosion–corrosion resistance and the paths for the erosion resistance enhancement of ceramic and coating materials are considered. Ceramic components design, technology, and installation features are reviewed.

“…The backing supports the ceramic and brings the comminuted ceramic and the projectile to rest. The backing material is selected on the basis of structural, ballistic, and weight considerations [13][14][15][16]. Many modern armours are regularly subjected to automatic weapon fire, where multiple bullets are fired towards a single location.…”

“…However, such limitations as multiple-hit capability have been recognized, which necessitates the development of new and more advanced materials. One of the ways that this can be achieved is by reducing the plate size so that if one plate has been destroyed providing protection from a single projectile, the area exposed to subsequent strikes is minimized [13][14][15][16]. The size of the plate is also important for the ballistic testing of the ceramic.…”

Influence of ceramic properties on the ballistic performance of the hybrid ceramic–multi-layered UHMWPE composite armour

et al. 2020

The present research involves studies of the influence of the physico-mechanical properties of the ceramics on the ballistic resistance of the new concept of the hybrid, ceramic–multi-layered UHMWPE composite armour developed using SiC and Al2O3 ceramics differing in thickness. Ballistic verification of new design of the ballistic composite armour was conducted in the scope of the protection against more than one shot (multi-hit) using 7.62 × 39 mm MSC and 5.56 × 45 mm SS109 ammunition. Tests of physico-mechanical properties, covering the determination of density, acoustic impedance, Young’s modulus, hardness, and resistance to brittle fracture, were conducted for the ceramic materials. Obtained results show that the ballistic behaviour of the testing system based on ceramic tiles being made of the same materials (SiC or Al2O3) of the different thicknesses does not directly correlate with the hardness, brittle fracturing, or Young’s modulus of ceramics. For ceramic plates of the same thickness being made of different materials in chemical terms, performed studies have shown that the ballistic resistance of the testing system does not only depend on acoustic impedance of ceramic plates, which should be as similar as possible to the acoustic impedance of the backing material in the ballistic armour, but also the resistance to brittle fracturing K1c is an important parameter of the ceramic plates entering the composition of the armour, and it should be as high as possible. Only the combination of these two properties yields the best ballistic protection of the armour when testing using the multi-hit procedure with the use of 7.62 × 39 mm MSC and 5.56 × 45 mm SS 109 ammunition.
