“…Plastics are widely used in the design of machine components (Skowrońska et al, 2021). Their satisfactory mechanical properties, combined with good tribological properties, self-lubrication and the possibility of modifying the composition, allow them to be used in elements such as gears, pumps and others (Chihai et al, 2019;Krawczyk, 2021;Kujawa et al, 2019;Li et al, 2021;Majdič & Strmčnik, 2019;Zhang et al, 2021). Manufacturing large sliding surfaces, such as the inner surface of a cylinder, from thermoset materials, requires specialised manufacturing methods.…”

The paper presents tribological tests of selected materials used as liners in a composite hydraulic cylinder. Three coating materials were used for the analysis: Sika F180 polyurethane, Huntsman Araldite LY1564 with Aradur 3487 amine hardener and Bezlona 1111 Super Metal. In addition, uncoated carbon epoxy laminate (CFRP) samples were used as reference material. The instantaneous course of the friction force, its maximum and average value, were the analysed parameters. Ball-on-disk tests were performed on a specialised tester that allows, among other things, to control the operating conditions (clamping force, operating temperature, speed, friction path) and measurement of the instantaneous value of the friction force. After these tests, the friction paths were observed using a Leica DCM8 contactless profilometer with an EPI 20x lens. The amount of energy dissipated due to friction was also determined. The conducted tests and comparative analyses allowed to conclude that the F180 material is the most desirable in terms of tribological properties.
