초록

${Ti}_{5}{Si}_{3}$${Ti}_{5}{Si}_{3}-{ZrO}_{2}$ 복합재료의 연소합성에 미치는 전기장의 영향에 관하여 연구하였다. 45mole% 이상 첨가한 ${Ti}_{5}{Si}_{3}-{ZrO}_{2}$ 복합재료는 전기장하에서만 연소합성할 수 있었다. ${Ti}_{5}{Si}_{3}$-45mole% ${ZrO}_{2}$와 Ti5Si3-60mole% ${ZrO}_{2}$ 복합재료는 전기장을 가하지 않은 상태에서는 불안정한 연소파가 전파되었지만 반응은 완전히 일어나지 않았다 즉, 불안정한 연소파는 시편의 중앙 부근까지 전파 된 후 멈추었다. ${Ti}_{5}{Si}_{3}$-ZrO2 복합재료의 연소파 속도는 시편에 가해준 전기장에 의해 약간 증가하였다.
