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...
