Regularities of tribological behavior of aluminum alloys at adhesive friction with increased temperature in the friction zone

Tribological behavior of aluminum alloy at elevated temperatures tests is investigated. It is revealed that at increase in temperature the adhesive component in the process of friction increases up to certain value, after which there is a decrease in adhesion and decrease in setting of the counter body and sample material. The morphology of the friction surface varies from the friction paths with a stepped structure to the scaly structure and then to the smoothed state of the friction path
