Abstract
A comparative study of the wear resistance and hardness of samples of A1100 grade aluminum grade, C11000 grade copper, 518.0 aluminum–magnesium alloy, and C95200 bronze obtained by the metallurgical method without and with nanostructural processing has been studied. Wear resistance of samples of metals and alloys was determined on a four-ball friction machine equipped with a special friction unit. The hardness was tested using the Brinell method on a Zwick/Roell Z050 universal testing machine. Electron and atomic force microscopy were used to determine the type of structure of the samples. It is shown that nanostructuring of these non-ferrous metals and alloys has a significant impact on their resistance to friction wear and hardness. An increase in the wear resistance of samples by 11–28% with a corresponding increase in hardness by a value of 12–15% was found.
