Loss Method

The effect of Alchornea Cordifolia leaf extract on the mechanical properties of mild steel in acidic medium was studied using weight loss method. The first sample was not introduced to any medium. It served as the control1 sample. The second sample was introduced to a medium containing 0.2M Sulphuric acid solution in the absence of the Alchornea Cordifolia leaves extract for 21 days, while the third sample was immersed in a vessel containing 0.2M sulphuric2 acid and 0.5g/L of Alchornea Cordifolia leaves extract as an inhibitor for 21 days. Results obtained showed a substantial improvement on the mechanical properties of mild steel exposed to the medium with the inhibitor.

Inhibitive Action

Corrosion behavior of mild steel in acidic medium usingAdhatoda Vasica(AV) extract was investigated. The inhibitive effective ofAdhatoda Vasicaon the corrosion of mild steel in different acidic medium has been studied by weight loss and polarization methods. The Ecorrvalues are shifted slightly towards negative side in presence of inhibitors which indicate the inhibitors inhibit the corrosion of mild steel in acids solution by controlling both anodic and cathodic reactions due to the blocking of active sites on the metal surface. It is evident that inhibitors bring about considerable polarization of the cathode as well as anode. It was, therefore, inferred that the inhibitive action is of mixed type.
