中文摘要 | On Cu-Zr-Ti amorphous ribbons, a lot of worm-like traces or quasi-continuous traces of cathode spots have been clearly observed using a scanning electron microscope (SEM). This kind of trace is eroded by the motion of a single spot step by step, and could not be observed on cathodes made of crystalline materials. Spot motion direction can be identified from the trace. The arc spreading velocity and spot lifetime can also be evaluated by these traces on SEM photographs, and they are 2.3 m s(-1) for arc spreading velocity and (1.10 +/- 0.32) mus for spot lifetime. Previously, these could only be measured using high-speed photographs. A linear relationship was found between the length of spot displacement and number of steps, which is quite different from that obtained by high-speed photographs, which fit Gaussian curves and a Rayleigh function. Possible reasons for this discrepancy are discussed. |
