Environmentally friendly paint coating using the sacrificial cathodic protection mechanism can be an alternative to toxic paints and also environmentally hazardous electro plating processes.
Low-carbon steels corrode in most of the atmospheric environments when the relative humidity exceeds 60%. Corrosion is the destruction or deterioration of a material because of reaction with its environment. Most common corrosion control methods use coatings and conversion layers, which contain toxic and environmentally hazardous materials. There is a need to find nontoxic and environmental friendly alternatives compatible with current industrial techniques.
