Abstract

Titan carbide based nano-crystalline solid solutions TiC + Ni (10 %) have been obtained by the chemical synthesis method in reaction between titanium hydride compounds and carbide-forming and binding components. Nickel has been chosen for the binding metal. Theoretical thermodynamic analysis performed for the ternary system (Ti – C) – Ni (10 %) has shown that TiC and TiNi compounds are able to be formed within the wide interval of concentrations, (28 – 48) wt. %. On purpose obtaining of the TiC + Ni (10 %) nano-crystalline powders titanium hydride, nickel chloride and soot were used as starting materials in charges molar-ratios as Тi:C:Ni = 1:1:0.1. Obtained product TiC + Ni was a black agglomerated nano-crystalline powder. Then, produced powders have been compacted in two stages applying specially elaborated spark-plasma-synthesis plant. Full-stroke compacting of powders takes (3 – 4) min. Proposed method of synthesis allows the retaining of a nano-crystalline structure even in compacted samples and goods.
