摘要
采用喷砂和真空蒸散技术,改进了Ni海绵氧化物阴极制备方法。试验表明,这一改进可显著提高阴极制备质量,有利于提高大功率微波器件的可靠性。
The preparation method of the Ni sponge oxide cathode has been reformed by spouting sand and vacuum evaporating technology. The results show that the performance of the oxide cathode can be improved by these new methods, which have advantages to improve the reliability of the high-power microwave device.
