description: The subject of the graduate qualification work is: "Investigation of friction and wear of materials based on aluminum, dispersion-strengthened with carbon par-ticles". This work is devoted to the study of the mechanisms of friction and wear of composite materials based on aluminum, dispersion-strengthened with fullerene soot. Tasks that were solved during the experiment: 1) Preparation and analysis of aluminum-based composite powders reinforced with carbon particles.2 ) Compaction of composite powders by hot pressing. 3) Study of the mechanisms of friction and wear of compact materials. 4) Analysis of the obtained data of the experiment on friction and wear. The research work was carried out at SPbPU of Peter the Great. Composite powders based on aluminum, dispersion-strengthened with fullerene soot, were obtained by powder metallurgy methods: grinding in a planetary mill and in a âdrunken barrelâ gravity-type mixer. The analysis of obtained SEM images of powder particles was carried out. A compact aluminum-based material reinforced with fullerene soot was fabricated by hot pressing. Friction and wear tests were carried out under various conditions. The analysis of the obtained friction tracks during the testing of materials was carried out and the hardness was measured. A metallographic analysis of the prepared etched sections was carried out and the microstructure of the materials was evaluated.
