Fabrication and wear resistance of Al-Cu-Fe quasicrystal-epoxy composite materials
Wear resistant polymer composites are prepared using a novel filler material, Al-Cu-Fe quasicrystals (QC). Novolac epoxy filled with Al-Cu-Fe quasicrystalline powder are evaluated by pin-on-disk testing using a 52100 steel counterface. Epoxy samples filled with aluminum, copper, iron, aluminum oxide, and silicon carbide are tested for comparison. The use of Al-Cu-Fe QC powder, as a filler in epoxy, maximizes the composite wear resistance while minimizing abrasion of the 52100 steel counterface. Wear mechanisms of the Al-Cu-Fe composites were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. The fabrication and wear properties of these unique materials will be described. © 2003 Elsevier B.V. All rights reserved.
