Compact ceramic electrode materials based on the Ti–B–Fe system modified with nanosize particles of aluminum nitride (up to 15 wt.%) are prepared by SHS extrusion. The effect of additives on combustion characteristics of the system and also on structure and phase composition of the materials obtained is studied. Addition of aluminum nitride increases the content of boride and nitride phases in the final product. It is established that introduction of modifying nanosize aluminum nitride particles into an initial charge leads to boride and nitride phase grain refinement that in combination increase microhardness by 10% compared with unmodified specimens.

SHS-挤压法制备纳米AlN粒子修饰的Ti-B-Fe体系致密陶瓷电极材料

通过SHS挤压制备基于Ti-B-Fe系统的紧凑陶瓷电极材料，并用纳米尺寸的氮化铝颗粒（最高15 wt。％）改性。研究了添加剂对系统燃烧特性以及所获得材料的结构和相组成的影响。氮化铝的添加增加了最终产物中硼化物和氮化物相的含量。已经确定，将改性纳米尺寸的氮化铝颗粒引入初始电荷会导致硼化物和氮化物相晶粒细化，与未改性的样品相比，微晶硬度相结合可将显微硬度提高10％。
