CORROSION BEHAVIOR OF Cu-Nb AND Ni-Nb AMORPHOUS FILMS PREPARED BY ION BEAM ASSISTED DEPOSITION F.Zeng1,F.Pan1,B.Zhao1,D.M.Li1 (1.Laboratory of Advanced Materials, Department of Materials Science and Engineering, Tsinghua University,Beijing 100084, China) Abstract:The Cu25Nb75 and Ni45Nb55 amorphous films with about 500nm thickness were prepared by ion beam assisted deposition (IBAD......
for electrification of mineral particles by electron beam irradiation was proposed. The effect of irradiation dose on charge/mass ratio was investigated experimentally. The charge/mass ratio of electrified mineral powders after irradiation was measured by an instrument based on the principle of electrostatic induction. The experimental results showed that the charge/mass ratio is largely dependent......
