Abstract

I- The introduction part deals with a general survey of the literature of the electrochemical and corrosion behavior of Pb and 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 alloy 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 ofthe 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.
II- The Experimental part deals with the preparation of Pb and Pb-In alloys (0.5%, 1.0%, 5.0%,10.0% and 15.0% In by atomic weight) electrodes. Full description of polarization cell, electrolytes (sulphuric, phosphoric and hydrochloric acids solutions ) and techniques were given. Also in this part the preparation of organic inhibitor solution (phytic acid) used in this investigation was stated. The surfaces before and after experiments were examined by X-ray diffraction, SEM and EDX.
III- The third part deals with the results and discussion obtained from the figures and tables. This part was classified into the following:
