Effect of Indium Content on the Electrochemical and Corrosion Behavior. Of Pb-In Alloys in Acidic Solutions and Inhibitive Action of Some Organic Compounds

      Аннотация: The introduction part deals with a general survey of the literature of the electrochemical and corrosion behavior of Pb-In alloys. The literature survey showed that there is no any work has been done on the electrochemical and corrosion behavior of Pb-In alloy in acidic solutions and only one paper was found on the photoelectrochemical behavior of Pb-In in alkaline solution. A careful examination of literature reveals that phytic acid has not almost yet been used as a corrosion inhibitor of Pb and its investigated alloys. So the aim of the present work is to investigate the effect of phytic acid concentration as green inhibitor on the corrosion behavior of Pb and its investigated alloys in HCl solution at different temperatures. The experimental part deals with the preparation of Pb and Pb-In alloys as electrodes. Full description of polarization cell electrolytes and techniques were given. Also in this part the preparation of organic inhibitor solution used in this investigation was stated. The surfaces before and after experiments were examined by X-ray diffraction SEM and EDAX.
