分析了高低压复合微能放电沉积的实现条件,提出了利用高压击穿放电间隙的方法,提高沉积加工过程的稳定性。对高电压条件下的放电特点进行了实验观察,通过改变放电能量获得了稳定的加工效果。最后,进行了单点沉积和轨迹连续沉积的实验,结果表明:该方法能有效提高沉积效率及沉积层的连续性。

The realization conditions of micro energy discharge deposition of high voltage and low voltage combined machining have been analyzed. The proposed method which was using high voltage to breakdown the discharge gap in air can increase the stability of the deposition process obviously. The discharge characteristics of high voltage discharge have been observed,and the stable machining effect was obtained in proper the discharge energy. The experiments on single point deposition and continuous deposition were carried out. The results show that the presented method can improve the deposition efficiency and the continuity of deposition layers evidently.
