| Abstract | ||||
| The inhibitive impact of eco-friendly Polyester (Glyptal) on the corrosion behavior of mild steel was examined. The inhibitory impacts were considered on mild steel in 1 M hydrochloric corrosive solutions, utilizing weight loss, electrochemical estimations, and Scanning Electron Microscopy (SEM) systems. The inhibitory impact was considered by adding different concentrations of inhibitors (100, 200, 400, 500, and 1000 ppm) by weight of the solution. The corrosion of steel was inhibited ceaselessly with the amount of inhibitor added. It came to a high state of inhibition with 500 and 1000 ppm of inhibitor concentration. SEM investigation uncovered that the expansion of inhibitor impedes the consumption forms, where the inhibitor is covering the outside of the metal, so it forestalls the metal surface to be in contact with the corrosive medium. | ||||
