【 摘 要 】

The hybrid powders AlMg6/C60 + 10-70 wt.% Al2O3 and AlMg6/C60 + 10-70 wt.% AlN were obtained by the method of mechanical synthesis in a planetary ball mill. These powders were used to create coatings using cold gas-dynamic spraying. The influence of the type and concentration of ceramic reinforcement on the growth efficiency and microhardness of the formed hybrid coatings was studied. It has been found out that the use of ceramic particles of AlN (up to 50 wt.%) as a reinforcement contributes to a more efficient growth of the coating compared to Al2O3. At the same time, the microhardness of coatings reinforced with AlN is lower than that containing Al2O3.
