The erosion hindrance of carbon steel in 1M HCl in nearness and nonappearance of terminated Hydrocortisone Sodium Succinate has been examined utilizing mass-loss. Comes about gotten appeared that the restraint productivity expanded with the increment of the concentration of the utilized medicate and diminished with the increment of temperature. The adsorption of this sedate on carbon steel surface takes after Langmuir’s adsorption isotherm. A few thermodynamic parameters were calculated. The motor parameters of erosion of carbon steel in HCl arrangement have been examined. Keywords: Corrosion inhibition; Carbon steel; Hydrocortisone

The chemical technique was used to investigate the inhibition and adsorption properties of L-proline for steel corrosion (weight loss method). As the concentration of L-proline increased, the inhibition efficiency increased, but decreased as the temperature increased, according to the findings. The inhibitor’s adsorption to the steel surface has been shown to be random, involving both electrostatic and chemisorptions. The Temkin adsorption isotherm governs the adsorption of L-proline to the steel surface. Thermodynamic parameters have been determined in some cases.
