本文采用多相悬浮混合法，对ZrO2/SiC-MoSi2复合材料制备过程中纳米SiC和ZrO2
颗粒均匀分布在基质MoSi2中的分散工艺进行了研究。以水和无水乙醇为分散介质,以PEG、PAA－NH4和PMAA-NH4作为分散剂分别对纳米SiC和ZrO2进行分散实验。同时研究了SiC纳米颗粒的表面预处理工艺对其分散性的影响。Zeta电位测试和沉降实验结果表明，采用550℃、2h的煅烧工艺处理纳米SiC可有效改善其分散性。使用水作为分散介质的分散效果均比乙醇好。ZrO2在分散剂为PAA-NH4，SiC在分散剂为PMAA-NH4时的分散效果最好。各种分散剂的加入量为0.2 wt%时的分散效果最好。ＳＥＭ结果表明通过以上最佳分散工艺得到的ZrO2/SiC-MoSi2复合粉体的均匀性较好。

1.1高频群脉冲电化学加工电流信号描述
电化学加工中用脉冲电源取代直流电源而出现的脉冲电化学加工，由于极大改善了阴阳极极间间隙流场特性，从而使电化学加工的精度得以显著提高向精密加工领域迈进。高频群脉冲电化学加工是基于加工微小型工件而提出的，电源群脉冲形式如图所示。
