摘要：

Samples of oxidized metal powders (Ag, Al, Cr, La, Nb, Ni, Ti) were repeatedly contacted with a gold plate under high vacuum conditions. The charge transfer was measured on both the samples and the gold plate. We observed charge saturation after one contact in most cases. Positive and negative polarities were detected. The charge densities were calculated and correlated with work functions of oxidized metals. Contact electrification of aluminum shows exceptional behavior with repeated contacts.
