Abstract


Inhibitive action of the extracts of Phyllanthus amarus and Acalypha indica on the corrosion of steel in epoxy resin has been studied using weight loss method, acid attack test, pull out strength test, acceleration test. In 50ml of Phyllanthus amarus and Acalypha indica extract and 25ml of epoxy resin are applied in coating of steel. The result from these characterization shows that Phyllanthus amarus, Acalypha indica extracted in epoxy resin exhibits better inhibition towards corrosion.
