Résumé
The presence of A12O3 particles in the composite coating promoted the formation of nanostructured aluminum in the transfer film, which contributed to its stability, as observed by in situ tribometry. This was linked to lower wear rates and more stable friction compared to the unreinforced cold sprayed aluminum. Here, the combination of in situ tribometry and ex situ analysis was a useful approach to reveal mechanisms specifically related to the transfer film, which were responsible for improved tribological performance. Other questions remain, which will be subject of future work, regarding the microstructural evolution in the wear track, mechanical properties of the third bodies, and the role of A1203 particles in the dynamic formation of nanocrystalline aluminum.
