Analysis of changes in the mechanical properties of the surface layers of aluminum alloys under the conditions of sliding friction

Resumo

In this article the properties of surface layers of aluminum alloys before and after friction tests of different durations are studied by the indentation methods and the impact of the composition of the alloys on these properties is revealed. It is shown that as a result of wear and tear, a pliable layer is formed on the surface of one of the alloys. Conclusions about various mechanisms of the wear and tear of alloys are made based on the analysis.
