| Abstract: | The influence of heat treatment on the corrosion behavior of two aluminium matrix
composites (AA2014/15 vol% Al2O3p - composite A and AA2009/20 vol% SiCw - composite B) was analyzed in 3.5% sodium chloride solution. The kinetic of the
corrosion process was studied based on the gravimetric measurements. The corrosion
damage and pit shape were analyzed by Image Analyzer. The corrosion damage in both
composites was caused by the pitting attack on the surface. Pit shape of the composite A
is different to the composite B. The corrosion rate of composite A is higher than
composite B because the voids or gap between reinforcement particles and matrix are
larger than in the composite B. The main attack of nucleation sites was at the interface region of the matrix and the reinforcement. |
