Abstract In the study, the corrosion behavior of aluminum matrix composites reinforced with boron carbide (B 4 C), silicon carbide (SiC) and alumina (Al 2 O 3 ) were investigated in saltwater (3.5 % NaCl). Composite materials were produced by powder metallurgy. For composite materials production, various reinforcement and aluminum powders were mixed by mechanical alloying for 4 and 10 hours. After mechanical alloying, mixed powders were compacted under 700 MPa pressure and sintered at 600 °C. Electrochemical corrosion tests were applied on specimens in the saltwater solution using potentiodynamic methods. According to the results of the investigation, the best corrosion resistance was obtained by aluminum/B 4 C and the lowest by aluminum/Al 2 O 3 composites.
