The Effect of Orientation and the Presence of Surface Active Materials on the Friction, Deformation and Wear of Aluminum
Abstract
Sliding friction experiments were conducted on single crystal and polycrystalline aluminum surfaces. The influence of the following on friction, deformation and wear were determined: (1) orientation of single crystals and textured polycrystalline sheet, (2) liquid metal embrittlement, (3) surface active organics, and (4) alloying with silver. Results indicate that friction and wear of aluminum is highly anisotropic. With single crystals, friction and wear are sensitive both to atomic plane and crystallographic direction of sliding. The presence of embrittling liquid metals on the surface of aluminum was found to reduce surface deformation during sliding. The presence of organic acids and alcohols were found to increase the deformability of oxidized aluminum surfaces.
