Polyamides containing Oxadiazole ring moiety as corrosion inhibitor for Aluminium in acid solution.

Corrosion control of metals is an important activity technical, economic, environmental, and aesthetical importance. The use inhibitors one the best options for protecting alloys against corrosion. This study involves investigation new effective polymeric material application corrosion inhibition on aluminium in acid medium using chemical electrochemical methods. Results obtained from weight loss potentiodynamic impedance methods confirm that polyamides containing oxadiazole rings their backbone can act as inhibitors. adsorption behaviour this polymer 1N HCl was found to obey Langmuir isotherm. SEM studies confirmed protective film formed by Polyamides.
