Abstract

The plastic alloys of PEEK/PEI/PES were prepared with extrusion molding at 370°C in ratios of 70/30/0, 70/25/5, 65/30/5, 60/30/10, 60/35/5 (w/w). Friction and wear behaviors of the alloys were investigated under dry sliding contact condition. And wear resistances of PEEK/PEI/PES alloys were considerably improved than pure PEI and PES. The friction coefficients of the alloys were higher than the pure PEEK for 0.2-0.3. The specific wear rates of the pure PEI or PES were 4-6 times as large as the specific wear rate for the alloys of PEEK/PEI/PES, and the specific wear rate for the alloys of PEEK/PEI/PES is 7~9 times as large as the specific wear rate of the pure PEEK. The plastics alloys would produce the transferred film containing PEEK on the steel counterface. However, the transferred film of pure PES or PEI was not found on the steel ring surface. A thin symmetrical and tough transferred film in the worn steel surface against the alloy specimens could reduce friction and wear. © 2012 Published by Elsevier Ltd.
