EMISSION OF HIGH-SPEED ELECTRONS AND OTHER PHENOMENA ACCOMPANYING THEPROCESS OF BREAKING ADHESION BONDS

The process of breaking adhesion bonds is accompanied by he drawing ap art of the plates of a flat condenser as formed by the double electric layer. An increase in the spacing between differently charged surface s in the process of breaking the adhesion contact results in the falli ng off of a capacity, and in increasing the potential difference up to the breakdown voltage. If the breakdown occurs under conditions of a vacuum, then during the experiment a flux of free electrons is registe red, whose energy amounts to a value of the order of 10(4) to 10(5) eV . Under ordinary conditions, owing to the ionization of the molecules of a surrounding gas by high-speed electrons, the gas-discharge proces ses arise accompanied by glowing, electromagnetic radiation, and acous tic emission, which are characteristic of those processes.
