title: EXPERIMENTAL EVALUATION OF WEAR RESISTANCE OF POLYMER MATERIALS USED IN PISTON COMPRESSOR EQUIPMENT
abstract: A new method is proposed for assessing the wear resistance of polymer materials according to the “finger — disk” friction scheme. It involves changing the geometry of the friction zone of polymer samples — the “finger” sphere is replaced by a truncated cone. The developed method is tested on samples of polyetheretherketone (PEEK) and polymer composite materials (PCM) based on polytetrafluoroethylene (PTFE, fluoroplast-4), in particular, obtained after laser ablation with the addition of carbon f
