Abstract

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.

用粉末冶金法制造用于气体动力喷涂的多重强化粉末

以 Al-6Mg 纳米晶基体为基础，用富勒烯（C60）和陶瓷颗粒（AlN）进行多重增强，对粉末进行了机械合成。研究了电荷中 AlN 含量（10 至 50 wt.%）对颗粒形态的影响，以及合成的多重增强粉末的粒度组成。分析了合成粉末的结构和相组成。使用动力学压痕法测量了多重增强复合粉末颗粒的显微硬度。结果表明，将陶瓷填料（AlN）的浓度从 10 wt. % 增加到 50 wt. %，粉末颗粒的显微硬度可比单增强复合材料颗粒提高约 12-20%。
