Abstract:

The effect exerted by various alloying elements added to AV000 aluminum on the thermal stability of the outer layer formed by D-1 lubricating oil containing 0.1 percent stearic acid was studied. The oil was spread on the aluminum surface during the frictional motion of a ShKh-9 steel ball on a circular aluminum bearing race. The chemical composition and some of the mechanical properties of the experimental specimens are summarized. All the experiments were conducted within the temperature interval of 20-360C, with the temperature changed in steps of 10-20C and the duration of each temperature step approximately 1 min. The addition of alloying elements increased the thermal longevity of the outer lubricating layer, the magnitude of the effect being proportional to the concentration of the added alloying element.
