Microencapsulated chemical(s), as water-soluble solid particles, are embedded in at least one the paint layers on the surface of a magnesium article used in an automobile. If the protective paint film is scratched or otherwise mechanically disturbed to expose the surface of the magnesium article the capsules will be ruptured. This will expose the encapsulated chemical(s) to ambient water enabling them to dissolve and form an aqueous solution capable of reacting with the exposed magnesium to form a protective passivating layer on the exposed magnesium to resist corrosion. In a second embodiment the encapsulated chemicals include a deliquescing compound for extraction of moisture from the atmosphere sufficient to induce dissolution of the passivating layer-forming chemical(s) and trigger the formation of the passivating layer in the absence of ambient water.

The invention discloses an intelligent response self-repairing anticorrosive coating material and a preparation method. The coating material comprises zinc oxide microcapsules and a coating matrix; each zinc oxide microcapsule comprises a capsule core and a capsule core carrier, the capsule core is a corrosion inhibitor, and the capsule core carrier is porous zinc oxide; and the outer surface of the capsule core carrier is coated with a ZIF-8 membrane. The porous inorganic material ZnO ensures the activity of the corrosion inhibitor, and the ZIF-8 membrane formed on the surface of the ZnO cannot only improve the bonding performance, but also serve as a hole sealing material to prevent premature release of the corrosion inhibitor. The invention successfully constructs the anticorrosive coating material with double effects of pH response and self-repairing. When the coating cracks, the microcapsules rupture and release the corrosion inhibitor, thereby realizing a self-repairing function; when no obvious damage is caused to the coating, and internal corrosion has already occurred, the microcapsules can be degraded and automatically release the corrosion inhibitor according to the change of pH value around a corrosion site, thereby realizing the self-repairing function.

A corrosion inhibitor is described which includes several supramolecular oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions preferably include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.
