In the current era, natural products extracts are used for corrosion inhibition activity. This method is an ecovative and non-toxic technique. Many researchers do their research on inhibition of corrosion on this green method. The efficiency of corrosion inhibition carried out by weight loss method. In the present study, the leaves extract of Adathoda vasica was studied as corrosion inhibitors by weight loss method. The variation of corrosion rate, percentage inhibition efficiency and surface coverage with increasing concentration were measure in this work.
