| Abstract | ||
| The aim of present work is to study the erosion –corrosion behavior of aluminum metal composite which consists of the (Al – 12wt % Si) alloy as matrix phase and 10wt% SiC particles as reinforcing phase. Composite material was prepared by stir casting using vortex technique. A general corrosion and erosion-corrosion for the base alloy and the prepared composite were carried out in 3.5wt% NaCl solution as corrosive medium for general corrosion while in erosion-corrosion ,with varying impact angles (0° ,30° ,45° and 90°) in slurry solution ( 1wt%SiO2 sand in 3.5wt% NaCl solution as the erodent). It was found that the general corrosion rate for composite specimen is lower than that of the base alloy (Al-12%Si). In case of erosion-corrosion results, it was found that the weight loss rate or corrosion rate in (gmd) unit at impact angle (0°) is lower than that of other impact angles for the base alloy and composite material. | ||
