Al/SiCp composites
In this work the degradation of metal/composite (M/C) interfaces in Al-Mg- Si/SiCp composites exposed to moist environments was investigated. The formation of Al(OH)3 at the M/C interface indicated the development of Al4C3 during processing. It was found that at room temperature Al4C3 slowly reacts with moisture in the atmosphere. As a result, the composite undergoes degradation with the degradation rate increasing logarithmically with time. In particular, it was found that the kinetics of degradation is influenced by the atmospheric conditions and the air quality.
