Emission Phenomena Accompanying the Triboelectrification Process in Vacuum

It was experimentally found that the triboelectrification of a dielectric is accompanied by the intense emission of high-energy electrons, both in the rolling friction and in the sliding friction. A detailed study was done in the electron emission during the course of triboelectrification in the process of mutual rolling of two dielectric rolls. The experimental results have shown that in triboelectrification the parameters of electron emission depend on the physico-chemical properties of the surfaces of contacting bodies.
