Abstract

The invention discloses a fast preparation method of TiB-TiC-TiB2-B4C composite ceramic, and belongs to the field of functional protection materials. The method is characterized in that TC4 powder and TiB2 powder are added into a ball milling tank; ball milling media are added; ball milling is performed, so that the mixture is uniformly mixed; drying is performed; mixed powder is obtained; the mixed powder is subjected to sintering treatment by a discharging plasma sintering system; the TiB-TiC-TiB2-B4C composite ceramic is obtained. The TiB-TiC-TiB2-B4C composite ceramic prepared by the method has the advantages that the density is high; the hardness is high; the intensity is high; the comprehensive performance is good; the TiB-TiC-TiB2-B4C composite ceramic can be applied to the field of protection materials.

Description

technical field [0001] The invention relates to a TiB-TiC-TiB 2 -B 4 The invention discloses a rapid preparation method of C composite ceramics, which belongs to the field of preparation of functional protective materials. [0002] technical background [0003] Protective materials with high ballistic performance, light weight, and strong secondary ballistic resistance are the goals of research in the field of armor. Wilkins first proposed a double-layer ceramic-metal bulletproof structure in 1960. Since then, many scholars have studied the bulletproof performance and mechanism of ceramic-metal composite targets and achieved a lot of results. Studies have shown that the ceramic material in the composite material can destroy the warhead and reduce the kinetic energy of the bullet during the penetration process, and its strength, hardness, high temperature resistance, toughness and other indicators are the key factors affecting the protective performance of the composite mate...
