TRIBOLAYER FORMED ON MULTIFUNCTIONAL COATINGS: INFLUENCE OF THE ENVIRONMENT

Friction and wear control can be achieved primarily by considering the nature of the counter faces, together with the environmental conditions. In most cases, a transfer film is found on the sliding surfaces. Environment plays a crucial role on the kinetics of formation and on the composition of t...

description Friction and wear control can be achieved primarily by considering the nature of the counter faces, together with the environmental conditions. In most cases, a transfer film is found on the sliding surfaces. Environment plays a crucial role on the kinetics of formation and on the composition of the transfer film, and thus strongly influences friction levels and wear rates. In this paper, the effect of the actual environment (refrigerant) present in hermetic compressors on the tribological behaviour of a Si rich multifunctional DLC coating deposited on 1020 steel is analyzed. Unlubricated reciprocating pin-on- disk tests are performed using a High Pressure Tribometer under different atmospheres (Air, CO2 and R600a). Samples tested in R600a environment present the lowest friction coefficient and the lowest wear rate for both body and counter-body
