摘要

采用钨铜复合材料作为微波管热离子阴极基体的起始材料。但脱铜对其显微组织有影响。为了减少脱铜过程中产生的损伤，研制了一种装置和实验方法。SEM分析了基体孔隙度(34.6%)，EDX测定了基体成分。

Development and characterization of the porous tungsten matrix obtaining process for dispenser thermionic cathode

W-Cu composites were used as starter materials of the thermionic cathode matrices for microwave tubes. However the decopperization affects their microstructure. An apparatus and an experimental procedure were developed to reduce the damages introduced during the decopperization. The matrix porosity (34.6%) was analyzed by SEM and its composition was determined by EDX.
