Abstract

lon implantation of O into Al and growth of Al(O) layers using electron-cyclotron resonance plasma and pulsed laser depositions produce composite alloys with a high density of nanometer-size oxide precipitates in an Al matrix. The precipitates impart high strength to the alloy and reduced adhesion during sliding contact, while electrical conductivity and ductility are retained. Implantation of N into Al produces similar microstructures and mechanical properties. The athermal energies of deposited atoms are a key factor in achieving these properties.

The high yield stress reported in this paper for Al80O20 (5.1 GPa) is in error due to incorrect indentation; the correct value is 1.7 GPa. The value for Al71O29 has changed slightly to 2.5 GPa due to refinements in the modeling.Google Scholar
