A cathode spot can remove an oxide layer. However, the influence of current change to the parameter of the cathode spot on the boundary layer remains unclear. As described herein, the number of cathode spots, the split frequency, the brightness and the areas on the surface of boundary layer when the current changed were measured. 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.\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.
