A cathode spot can remove an oxide layer. However, the influence of pressure change to the parameter of the cathode spot on the boundary layer remains unclear. This study elucidated the split process and frequency in order to know the removal process of vacuum arc cathode spot with vapor from oxide layer. As described herein, the number of cathode spots on the surface of boundary layer were measured when the pressure changed. Experiments were performed using a SS400 cathode and a cylindrical copper anode. A high-speed video camera recorded the cathode spot movement. Then, the obtained images were analyzed using plasma image processing. The number of cathode spots decreases with increasing the pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語): \u003c\/strong\u003eA remarkable characteristic of a vacuum arc cathode spot is that the cathode spot moves around on the metal surface.
