About a negative-ion concept of the antiwear and antiseizure action of hydrocarbons during friction

A new negative-ion concept of the mechanism of lubrication of hydrocarbons has been derived. The thesis of the concept is based on the mechanism of ionization of saturated and aromatic hydrocarbons caused by the action of exoelectrons.

Description
Summary:A new negative-ion concept of the mechanism of lubrication of hydrocarbons has been derived. The thesis of the concept is based on the mechanism of ionization of saturated and aromatic hydrocarbons caused by the action of exoelectrons. The following stages have been considered in the model: (a) the low energy electron (2–3 eV) emission process and creation of positively charged spots; (b) the reaction of the emitted electrons with hydrocarbon molecules adsorbed on the rubbing surface, leading to the formation of negative ions and radicals; (c) the reaction of the negative ions with the metal surface. The proposed model explains the untypical behaviour of these hydrocarbons under different atmospheres in the friction process.
