Friction of Inhibited Plastics

Tribology is a science studying friction, wear and lubrication, along with interactions of the contacting physical bodies during their mutual motion. [Pg.11]

Mechanical energy generated by the movement of the contacting bodies is converted by friction into other types of energy, leadings to triboelectric and tribochemical phenomena. [Pg.12]

When metal parts rub in an electrolyte, it is possible to form short-circuit galvanic microelements (Fig. 1.7). Potentials 1E3 and 2E3 appear at the metal-electrolyte interface and contact potential difference 1E2 in the contact sites of the parts. The electromotive force of these elements promotes electrode processes on the friction surfaces. The processes appear even though lEs = 2E3. because of the galvanic elements resulting from crevice corrosion in the friction zone. [Pg.12]

Friction and corrosion mutually affect one another. Friction violates integrity of the passivating layers on the friction surface of metal parts. Movement of the friction surfaces relative to each other accelerates supply of corrosion matter to the freshly formed surface areas of the mechanical counterbody and removal of the products of electrode reactions. These stages of the electrode process are less intensive in static conditions and follow the mechanism of diffusion or convection. As can be seen, corrosion serves as a catalyzer of mechanical wear during metal friction in electrol3Tes. Mechano-chemical [Pg.12]
