Anticorrosive performance of piperidinium-based ionic liquid on 6061 aluminium alloy in HCl medium
Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy methods were used to investigate the inhibitory effects of 1-methyl-1-propyl-piperidinium bromide (MPPB) on the corrosion inhibition of 6061 aluminium alloy in the presence of 0.01 M HCl. The results of PDP studies indicate that MPPB behaved as a mixed inhibitor. The inductive loop in the Nyquist plot implies the adsorption of MPPB on the surface of 6061 aluminium alloy. Scanning electron microscope and atomic force microscopic analysis indicated the adsorption of MPPB on the surface of 6061 aluminium alloy by smooth surface in the presence of MPPB. The percentage composition of aluminium is found to be more in the presence of MPPB than in the absence of MPPB in a corrosive medium, which implies adsorption of MPPB on 6061 aluminium alloy. From PDP studies, it is evident that MPPB gave a maximum inhibition efficiency of 73.95% in 0.01 M HCl for 400 ppm of MPPB at 303 K.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
