Abstract : Metal-matrix composites suffer from preferential corrosion because of their non-homogeneous composition and structure. In particular, aluminum alloy matrix materials are very susceptible to corrosion, when the dispersoid is a noble phase, such as SiC. This paper describes the pros and cons of what inadequate processing and fabrication can do to corrosion behavior of the composites. Keywords: Metal matrix composites; Aluminum silicon carbide; Extrusion; Preferential corrosion; Solution heat treatment; Polarization; Metallurgy.
