| Abstract: | Wettability of liquid A359 alloy on SiC particles under molten salt NaCl-KCl-NaF is found at 180 deg, meaning that SiC particles
prefer the molten salt phase against the Al phase or the Al/molten salt interface. Thus, this molten salt can be used for
recycling, i.e., to separate the phases in the SiC reinforced Al matrix composites. If the separation process is interrupted, Al droplets
(submillimeter solidified powder) can be produced, stabilized/surrounded by a monolayer of shielding SiC particles. |
