The research work was based on the comparative study of the corrosion bebaviour of the mild steel using agitated distilled water with 0.5 mol and 0.3 mol of Na2SO4 solution. The materials used for the research work are welded and un-welded mild steel. The mild steel materials were obtained at the Foundry shop of the Ajaokuta Steel Company Limited. The mild steel materials were analyzed using the SPECTRO Analytical Instruments at the Foundry shop of the company. These experiments were performed using 0.5mol and 0.3mol of Na2SO4 in different agitated media of distilled water .The samples used for general corrosion studies were 10mm and 4mm mild steel thickness. These materials were cut into specimen sizes to 2cm by 2cm). Twenty -eight (28) specimens each were prepared for the 10mm and 4mm mild steel materials the samples were ground and polished on the emery papers which removed rust particles on the test materials. The specimens were exposed for days for over fifty –four (54) days, with an interval of 3days. It was observed that welded materials have higher corrosion rate than the un-welded materials when subjected to experimental conditions. The corrosion rates values were used to plot graphs against time of exposure.

Human tear comes in contact with a number of instruments during operation in the eyes.  This results in a variety of undesirable effects such as corrosion and malfunction.  Corrosion behaviour of five metals, namely, mild steel (MS), mild steel coated with zinc (MS-Zn), Ni-Cr, Ni-Ti super elastic (Ni-Ti.SE), and SS 316 L in artificial tear solution has been studied by polarization study and AC impedance spectra.  The study reveals that the decreasing order of corrosion resistance in artificial tear solution is : Ni-Ti SE > Ni-Cr > SS 316 L > MS-Zn > MS.  The first three metals are better candidates and the first one is the best candidate for making instruments used in operation in the eyes, in presence of tears.
