陶瓷材料的SHS超快速致密化技术
PROCESS FOR SHS ULTRA-FAST DENSIFICATION OF CERAMICS
摘要
Abstract
Combining self-propagation high-temperature synthesis (SHS) with hydraulic quick pressing (QP) in a single processing operation, dense ceramics can be fabricated rapidly. Immediately after SHS, when the sample is still red-hot and soft, a quick and large mechanical force is applied to the sample. The densification of the sample can be achieved in several minutes. The mechanism of densification in such a short time is still not clear. In this paper, the SHS/QP densification mechanism for ceramics is discussed.The processes for the making of multi-phase ceramics, layered materials and nano-ceramics were studied. The results show that dense ceramics with finer grains can be obtained by the SHS/QP technique. The process also revealed the densification mechanism based on plastic deformation.关键词
