Cathode spot propagation on the surface of amorphous, nanocrystalline and crystalline Cu60Zr28Ti12 cathodes
Physics Letters A 318(2003)435-439,-0001,():
Arctracks on the surface of coarse crystalline, amorphous, and nanocrystalline Cu60Zr28Ti12 cathodes were investigated. On the surface of coarse crystalline Cu60Zr28Ti12, cathode spots were restricted to a small zone, while on the surface of amorphous and nanocrystalline Cu60Zr28Ti12 cathodes, the spots spread over a wide area, of about 15×2.4mm2 and more. The arc tracks on the amorphous ribbons had a worm-like form, which is attributed to continuous cathode spot motion. The arc track on nanocrystalline Cu60Zr28Ti12 alloys, crystallized from the amorphous alloy, consisted of densely distributed~3 μm craters.
