Experimental Evaluation of Wear Resistance of Polymer Materials Used in Piston Compressor Equipment

Механика машин, механизмов и материалов
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 ...
