ABSTRACT
We investigated the effect of filled with corrosion inhibitors or empty inorganic nanocontainers, water, and chlorine microspheres in the barrier properties and general performance in the anticorrosion protection that can offer a hybrid inorganic-organic coating on magnesium alloy ZK30. Initially, the synthesis and characterization of three types of nano- and microspheres are described: first, the formation of inorganic cerium molybdenum oxide nanospheres loaded with corrosion inhibitors; second, the manufacture of inorganic microspheres that act as traps of chlorine ions; and third, the manufacture of organic microspheres that act as ion traps of water. We evaluated a number of inhibitors with respect to their efficiency to protect ZK30. Finally, we evaluated five samples with different compositions and demonstrated that self-healing occurs in the samples containing CeMo filled or not filled with inhibitors. We also demonstrated the benefit of using water and chlorine microtraps into the anticorrosion coatings.
