Abstract: Microcapsules using Polyvinyl Alcohol (PVA) or glutin as membrane, lubricating oil, benzotriazole inhibitor or hydrophobe as core are prepared by the method of separation in water phase. High corrosion resistance function composite coating by codeposition of these liquid microcapsules with copper and nickel ions is obained. Compared with the rusting time on 5% NaCl solution, the time of composite nickel coating containing rust preventive oil microcapsules is 40 times that of the nickel coating without microcapsule. Compared with the corrosion time on nitric acid and ammonia solution dropping test, the composite copper coating containing benzotriazole inhibitor microcapsules is 3 times that of the copper coating without microcapsule. Anode polarization curve and regularity of electrode potential changing with time on acid copper plating solution are studied and the results show that the composite coating containing hydrophobe microcapsules has higher corrosion-resistance function than copper coating.
