TL;DR: In this article, the pitting potentials are essentially independent of the presence or absence of reinforcement particles, as well as their volume fraction, and the presence of intermetallic particles strongly affects the corrosion and titanium/zirconium-rich particles have a particularly deleterious effect on corrosion of the 6061-Al alloy.
Abstract: : Long term immersion testing and short term electrochemical testing have been carried out on two metal matrix composites and their corresponding unreinforced alloys. The composites were 15% alumina reinforced 6061-Al alloy and an Al-Si alloy reinforced with 20, 30, 40 or 55% SiC particles. It is shown that the pitting potentials are essentially independent of the presence or absence of reinforcement particles, as well as of their volume fraction. Corrosion i shown to be generally more severe in the composites than in the unreinforced alloy and weight loss rates may be 3 or 4 times greater. The presence of intermetallic particles strongly affects the corrosion and titanium/zirconium-rich particles, believed to arise as a consequence of the processing route, have been shown to have a particularly deleterious effect on corrosion of the 6061-Al alloy.
