Fabrication of multi-reinforced powders for gas-dynamic spraying by powder metallurgy
Mechanical synthesis of the powders based on the Al-6Mg nanocrystalline matrix, multi-reinforced with fullerenes (C60) and ceramic particles (AlN), was performed. The effect of the AlN content in the charge, ranging from 10 to 50 wt. %, on the morphology of particles, and the granulometric composition of the synthesized multi-reinforced powders were studied. The structural and phase composition of the synthesized powders was analyzed. The microhardness of the multi-reinforced composite powder particles was measured using kinetic indentation. It was shown that by increasing the concentration of ceramic filler (AlN) from 10 to 50 wt. %, it becomes possible to increase the microhardness of the powder particles by about 12–20% compared with the mono-reinforced composite particles.
