Effect of normal load and sliding velocity on the Wear rate of some polymer blends

Abstract

The paper investigates experimentally the effect of normal load and sliding velocity on wear rate of some polymeric blends consists of Epoxy Resin (EP), unsaturated polyester (UP) and Poly Vinyl Chloride (PVC), prepared by Hand – lay up molding with different weight ratios, at room temperature . Experiments were carried out under normal loads (5,10,15,20) N and sliding velocity (3.14,3.92,4.71) m/sec before and after the immersion in (HCL) solution with normality (0.3 M) . Experimental results show that the wear rate increases with increasing normal load and sliding velocity for all samples before and after immersion in (HCL) solution (21) days. Also the results show that the wear rate for immersed samples in (HCL) solution higher than that of dry samples .
