BAZALT DOLGULU POLİMER KOMPOZİTLERİN AŞINMA DAVRANIŞLARI

In this study, pin-on-disc wear tests of basalt filled, one of the volcanic rocks as a filler material, (10-70wt.%)
LDPE polymer matrix composites were performed depending on various sliding speeds at 20 N loads under dry
sliding conditions. Wear tests were carried out with configuration of a polymer pin on a rotating AISI 4140 steel
disk in the atmospheric conditions under the loads of 20N and at the sliding speeds of 0.5 m/s and 1.5 m/s. The
results showed that increase in basalt content of the basalt filled LDPE composites resulted in a decrease of the
friction coefficient and wear rate. While the friction coefficient of LDPE composites was changing between
0.11 and 0.51 and basalt content of the polymer composites, and wear rates of the basalt filled LDPE composites
ranged from 7.18x10
