Abstract
The use of ecofriendly corrosion inhibitors in acid cleaning solutions for metals surface before coating application is of particular interest. The extraction from plants as abundant and cost-effective resources is one of approaches to obtain ecofriendly corrosion inhibitors. This paper introduces the extraction methods and the variety of the plants used to prepare corrosion inhibitors. In addition, the inhibition mechanisms anodic, cathodic and mixed for various corrosive acid solutions and metallic substrates are introduced.
