Effect of Natural Products on the Corrosion of Titanium and Its Alloy in NaOH Solutions

The corrosion behavior of pure titanium and Ti-6Al-4V alloy in different concentrations of NaOH was investigated by using different techniques. The effect of bovine serum albumin and egg albumin on corrosion behavior of pure titanium and Ti-6Al-4V alloy has been studied. It has been found that natural products such as (bovine serum albumin and egg albumin) inhibit the corrosion process of Ti-6Al-4V alloy more than pure titanium. The inhibition efficiency increases as the concentration of protein in the solution increases, as was confirmed by SEM.
