Friction processes of selected polymers sliding on steel and duralumin in a lubricant environment
The article presents the results of tribological research into engineering polymers (POM, PEEK, PPS) cooperating in sliding motion with 316L steel and EN AW 2017A aluminium alloy in the presence of a liquid (water, hydraulic oil HLP68) This type of friction pair may occur in hydraulic systems (gear pumps, valves, etc. For comparison, additionally, the results of tribological research Wroclaw University of Science and Technology, Faculty of Mechanical Engineering, Department of Machine Design and Tribology, ul. Wybrzeze St. Wyspianskiego 27, 50 370 Wroclaw, Poland. D. Serikbayev East Kazakhstan State Technical University in Ust Kamenogorsk, Kazakhstan. T R I B O L O G I A 4 2016 202 carried out in dry friction conditions have been shown. In addition, the results of microscopic study of the sliding surfaces of polymeric materials have been presented. Analysis of the test results allows one to describe the processes of friction and wear of the studied sliding pairs.
