Deterioration of metals in the form of corrosion is the major problem faced in almost all industries. Annual cost of corrosion world-wide has been estimated to exceed 3% of world’s GDP. Corrosion control of metals is an activity of economic, environmental, aesthetic, and technical importance. Zinc, one of the most important non-ferrous metals, has a wide range of applications in industry as well as in domestic sectors. It is used as a coating material on steel and iron. Corrosion of zinc and galvanized articles can be prevented by using chemical inhibitors. Even though they are proven to be effective for industrial applications, environmental hazards resulted as a consequence cannot be ignored. Over the last decades, research is more focussed towards the use of environmental friendly green inhibitors. In this regard, plant extracts have become important as an environmentally acceptable, readily available, and renewable source for a wide range of inhibitors. This review consolidates and documents an overview of the application of plant products as corrosion inhibitors for the corrosion mitigation of zinc.
