摘要：The effect of temperature on the inhibitive property of the Trigonella foenum graecum seeds (TfgS) onthe acid corrosion of aluminum has been investigated. The experimentation was carried out by the weight loss method.The results reveal that TfgS inhibit corrosion of aluminum very efficiently. The inhibition efficiency (IE %) was foundhighest 95.65% at the optimum concentration of TfgS at elevated temperature which decreases with further increase intemperature. The corrosion and thermodynamic parameters were determined in the studied temperature range fordifferent concentrations of TfgS. The G values indicate that the adsorption of TfgS on aluminum is physical in nature.The adsorptive behavior of the inhibitor at room and elevated temperatures was further studied by the FTIRspectroscopy and Optical micrography techniques. It can be inferred that the TfgS may be a better substitute of thechemical inhibitors used for acid corrosion of aluminum.
