Abrasive and fretting wear resistance of aluminum alloy specimens manufactured by laser microcladding.

In this article, the results of investigations of abrasive wear resistance and wear under the fretting of the samples obtained by the method of laser microcladding have been presented. The material for sample preparation was powder of Al-Si hypereutectic alloy with the following composition: 70-74 wt % Al and 26-30 wt % Si. The influence of the structure and phase composition of AlSi30 alloy on wear resistance under the conditions of abrasive wear and wear under fretting conditions has been shown. [ABSTRACT FROM AUTHOR]
