Abstract

Multilayer Ti–Ta–Ni–TiC–TiB composite (cermet) was obtained by combustion-aided joining in multilayer sandwiches formed by Ti–C and Ti–B reactive layers and metal foils (Ti, Ta, Ni) and characterized by thermographic analysis and rapid video filming. Thin plates of resultant composite (32 × 14 × 1.5 mm) were formed within 0.2 s after ignition (burning velocity 195 mm/s). Ta foils were found strongly joined with Ti ones due to development of high combustion temperatures in the reactive layers yielding TiC and TiB ceramics. The presence of ceramics afforded for reducing material density, on retention of its heat/corrosion resistance. Our results open up new horizons for SHS-assisted fabrication of new refractory materials with required structure/properties.

助燃多层Ti-Ta-Ni-TiC-TiB复合材料

摘要

多层Ti–Ta–Ni–TiC–TiB复合材料（金属陶瓷）是通过燃烧辅助结合在由Ti–C和Ti–B反应层以及金属箔（Ti，Ta，Ni）形成的多层三明治结构中的，并通过热成像分析进行了表征。和快速的视频拍摄。点火后0.2秒内（燃烧速度195 mm / s）形成合成复合物薄板（32×14×1.5 mm）。由于反应层中高燃烧温度的发展，发现Ta箔与Ti牢固地结合在一起，从而产生了TiC和TiB陶瓷。陶瓷的存在可以降低材料的密度，同时保持其耐热/耐腐蚀性能。我们的结果为SHS辅助制造具有所需结构/性能的新型耐火材料开辟了新的前景。
