The moving track of low pressure arc cathode spots for development of high speed removing method of oxide layer was elucidated by using the electrode of low pressure arc generation, algorithm of plasma image processing and high speed video camera. As a result, the cathode spot was split and united, repeatedly. In addition, the oxide layer is evaporated and blows up, when the cathode spots contact with the oxide layer and moves at the boundary, continuously. These phenomena were depended by the oxide thickness.

利用低压电弧发生电极、等离子体图像处理算法和高速摄像机，阐明了高速去除氧化层方法中低压电弧阴极斑点的运动轨迹。其结果是，阴极斑点分裂和联合，反复。此外，当阴极斑点与氧化层接触并在边界处连续移动时，氧化层被蒸发并吹胀。这些现象与氧化层厚度有关。
