Rulmanlı Yatak Uygulamaları İçin Grafit Katkılı PTFE ve PTFE Katkılı Poliamit-6 Polimerlerinin Aşınma ve Sürtünme Performanslarının Karşılaştırılması

This study was carried out to compare the tribological performances of 35wt.% graphite-added polytetrafluoroethylene (35G/PTFE) composite and 10wt.%PTFE filled polyamide 6 (10PTFE/PA6) polymer blend at different speeds used in rolling bearing applications. Tribological tests were on a pin-on-disc wear test rig sliding 1.0, 1.5 2.0m / under loads 50N 150N. Tests conducted against AISI 316L stainless steel disc material dry conditions room temperature. As result friction tests, it observed that coefficient values both materials experiments slightly affected by increase speed, while volume rate increased. obtained data, graphite PTFE is between 2.70 3.67x10-14 m2/N, 10wt.% PA6 5.07 to15.5x10-14 m2/N. 35% found be average 62% resistant than mixture.
