 The aim of this work was a comparative study of the wear resistance of a sample of an aluminum alloy (EN AW-2024, an aluminum alloy of the Al-Cu-Mg system) modified with ultrafine particles of minerals using the sclerometry method, which makes it possible to measure the physicomechanical properties of the material at the microscale, as well as determining some tribological parameters (hardness and elastic modulus) of a duralumin sample with a mineral coating. Wear resistance was measured using a NanoScan-4D scanning hardness tester using the multi-cycle friction method using a sapphire sphere with control of the pressing force and the deepening of the tip into the sample. The use of such a measurement system is especially important when testing thin modified layers,
when the layer thickness is comparable with the surface roughness parameters and the influence of the substrate is excluded. The measurement results showed that the wear resistance of the surface of an aluminum alloy sample
modified with ultrafine mineral particles increased by more than 12 times compared to the wear resistance
of an aluminum alloy surface without modification.
