Influence of tribological interaction conditions on the material transfer process during adhesive friction between Al-alloy and high-speed tool steel

In the present work, the study of sliding friction process of Aluminum alloy - steel pair was carried out in order to determine the influence of interaction conditions on the material transfer processes. The friction tests were carried out according to the “pin-on-disk” scheme, where tool steel T11302 was used as a pin, alloy AA5056 was used as a disk. The results of the study showed that the height of the transfer layer of aluminum alloy on the steel pin surface increases with the increase of normal load and movement speed. It is shown that the friction coefficient increases with the normal load. The movement speed does not affect the average value of the friction coefficient in any way.In the present work, the study of sliding friction process of Aluminum alloy - steel pair was carried out in order to determine the influence of interaction conditions on the material transfer processes.
