Vacuum arc technology is one of the dry processing, and it can treat the surface very fast. A cathode spot can evaporate the oxide layer and form a roughness. However, the influence of the parameter of the cathode spot with changing the current remains unclear. As described herein, in order to know the split process, the time variation of the number and area of cathode spots were measured with changing the current. 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. As a result, the parameter of the cathode spot was normalized by the current density and number. In addition, cathode spot had appropriate number and area with the time variation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語): \u003c\/strong\u003eThe surface treatment is expected for promotion of circulating production.
