Such metal-ceramic composites are prepared through the sol–gel deposition of iron-based coatings on alumina platelets and the magnetically-driven assembly of the pre-coated platelets into nacre. Graphene with excellent comprehensive properties has been considered as a promising filler to reinforce ceramics. Armor structures made of ceramic and ceramic composite materials have been widely used for ballistic applications to resist armor-penetrating projectiles. The lightweight design of ceramic materials and structures has attracted much attention. Overview. In this paper the interface-controlling parameters are described. It is an alumina matrix composite ceramic with high fracture strength 1, excellent wear properties 2 and outstanding biocompatibility. Such composites of metal and ceramics, so-called metal-matrix composites (also: metal-matrix composites, MMC), consist of a metal (matrix) reinforced with hard ceramic particles. Industrial ceramics are commonly understood to. Ceramics. The relatively strong interface strength between reinforcement and the ceramic matrix improves the strength but deteriorates the toughness by means of ensuring the high load-transfer efficiency in the ceramic composites (Fig.
