STUDY ON STRUCTURE AND PROPERTY OF Nb-DOPED TiC CERAMIC WITH QUANTUM CHEMISTRY CALCULATIONS

Nb-doped TiC ceramic,or (Nb_yTi_(1-y)) C_x, inwhich amount of Nb element added is increased from zero to40Wt.%, synthisized with self propagating high temperaturesynthesis, is studicd with SCF-Xa-DV,a quantum chemistry cal-culating method. The chemical bonding is studied to discuss therelation between structrues and properties. Several classes ofmodels in which there is no vacancy,one vacancy or two vacan-cies have been calculated. From the calculated results of bond or-der, a measure of covalent bond strength, and molecule orbitalcontotr map, it is concluded that when Nb element added in-creases, the vacancies increase correspondinigly, the covalent com-ponent of chemical bonds of the samples decreases while the met-al-bonding component increases, so the hardness and resistanceof the samples decrease.
