Effect of aluminum-alloy composition on self-lubrication of frictional surfaces

The influence of the mechanical and geometric characteristics of the hard and soft phases of an anti-friction alloy (yield limits of these phases, size and concentration of inclusions) on the amount of the solid lubricant appearing on the frictional surface is analyzed. The results obtained are used both to describe the existing anti-friction aluminum alloys and to give the recommendations for creating new wear- and score-resistant alloys.
