Abstract: | Aluminum matrix composites were produced via the plasma injection of reinforcing particulates into aluminum melts stirred
electromagnetically. In this process, a metallic wire supplied to the active zone of plasma torch disintegrated into fine
metallic particles. In the plasma arc, the particles are heated above the melting point and accelerated to close to sonic
speed, which helps with the incorporation of the particles into the melt. In this study, the possibility of producing aluminum
matrix composites reinforced by intermetallic compound particles via plasma synthesis is demonstrated. |
