Metal matrix composites (MMCs) are among the very important engineering materials by which the combinations of various properties can be achieved. The MMCs have the great potential for use in automobile and aerospace industries for possessing high strength, stiffness and hardness. The reinforcement types used in the composites are continuous, discontinuous, short, whiskers and particles. The at...

This study looked into the influence of iron nitrate (Fe(NO3)3 on corrosion behavior a 6061 Al alloy treated by plasma electrolytic oxidation coating (PEO). PEO coatings were fabricated samples under AC conditions utilizing an alkaline-aluminate electrolyte containing 0 and 5 gr Fe(NO3)3. Surface examination demonstrated that some Fe2O3 particles effectively integrated layer produced in solutio...
