In this investigation the influence of test load and roughness of steel on the friction and wear behaviour of polydicyclopentadiene (PDCPD) were studied. Friction and wear tests of PDCPD and R6M5 steel were carried out under dry friction and boundary lubrication on a pin-on-disc arran-gement. Tribological tests were performed at room temperature at different pressures (10 N and 18 N), the different roughness of steel (0.08 µm and 0.15 µm), sliding speed 0.5 m/s and sliding distance 3500 m. It is shown that under dry friction sliding, the wear increases with increasing pressure. In addition to this, decreasing of the roughness of steel from 0.15 µm to 0.08 µm reduces the wear intensity more than 2.0 times. It was found that in the presence of boundary lubrication friction coefficients are significantly reduced linearly with the decrease in viscosity of lubricants (polydimethylsiloxane fluids).
