论文摘要
除钻石外，钻石-SIC复合材料在现有材料中具有低密度和最高的声音速度。该复合材料是由钻石粉和液体SI之间复杂的放热化学反应合成的。这使其成为防止冲击负荷的理想材料。实验表明，在钻石界面上形成了模式系统。复合合成的反应扩散过程的建模证明了陶瓷材料在给定系统中具有规则（周期性的）互连微结构的形成。在界面处具有相互连接结构的复合材料具有很高的机械性能和抗击力，因为其分数是晶层。
The diamond-SiC composite has a low density and the highest possible speed of sound among existing materials except for the diamond. The composite is synthesized by a complex exothermic chemical reaction between diamond powder and liquid Si. This makes it an ideal material for protection against impact loading. Experiments show that a system of patterns is formed at the diamond-SiC interface. Modeling of reaction-diffusion processes of composite synthesis proves a formation of ceramic materials with a regular (periodic) interconnected microstructure in a given system. Composite material with interconnected structures at the interface has very high mechanical properties and resistance to impact since its fractioning is intercrystallite.
