项目摘要

For the development of new evaluation method for the sintering behavior by the direct measurement of interaction between powder interfaces, the applicability of the electrochemical impedance spectroscopy (EIS) in evaluating the mass transfer behavior under the sintering was experimentally investigated by the EIS measurements of molybdenum and cerium oxide compacts at high temperature. The impedance change corresponding to the change of interface such as neck growth and powder connection could be measured separately from that of bulk. From the result, there is the possibility that the mass transfer behavior at powder interfaces under the sintering could be evaluated by using EIS.

为了通过直接测量粉末界面之间的相互作用来开发新的评估方法，通过在高温温度下钼和氧化元素的友好量测量，通过EIS测量了烧结的炸药在评估烧结下的传质行为时，电化学障碍光谱（EIS）的适用性。可以与散装的界面变化（例如颈部生长和粉末连接）的变化相对应的阻抗变化。从结果中，可以使用EIS评估烧结下粉末界面处的传质行为。
