摘要
介绍了三维网络陶瓷增强复合材料的内部结构特点、主要制备方法以及摩擦磨损性能和抗冲击性能等研究进展。三维网络陶瓷/金属复合材料可以抑制基体合金的塑性变形和高温软化以及严重的三体磨损,使得复合材料的抗磨性能提高;这种结构有利于将集中在点或面上的应力迅速在空间体范围内分散和传递,提高复合材料的抗冲击能力;同时,这种三维双连续的结构还可能引起结构互锁的效应,使得材料具有更高的损伤容限,材料失效的危险性降低。
Internal structural characteristics, key processing methods, frictional and wear behavior as well as anti-impacting behavior of 3D network ceramic/metal composites were described. The wear resistance of the composites is improved as a result of 3D network ceramics restraining plastic deformation and high temperature softening of the matrix as well as serious three-body wear. Meanwhile, anti-impacting behavior of the composites is enhanced through dispersing and transferring the load imposed on point or plate spacially. In addition, the composites exhibit more damage tolerance, which is attributed to structural interlocking effects resulting from 3D double continuous structures, decreasing the failure tendency of the composites.
