INVESTIGATION OF MODERN NANO-COMPOSITE COATINGS USED IN PASSIVE CORROSION OF METAL STRUCTURES

Corrosion caused by the interaction of metal with environment is one biggest problems affecting country's economy. One easiest ways to prevent corrosion cover metals paint, plastic, or wood. Several types coatings based mainly on electrochemical principles have been adopted scientists corrosion. Fortunately, four are used in different and metallurgical industry, cost effectiveness. cheapest most effective use barrier such as powder, paint. Thus, nanocomposite deposition offer excellent scratch resistance surfaces. These can be restore components instead replacing them, resulting reduced maintenance costs inconvenience. Significant improvements protection steel reported using metal-metal matrix, oxide metal-polymer matrix ceramic-metal nanocomposite. This review provides an overview work re-evaluates literature for further research this still unproven field.
