| Abstract | ||
| ABSTRACT:- The aim of present work is to apply Barnartt`s three point method (TPM) and McLaughlin method on the corrosion rate data of mild steel and Cu-Ni alloy in hydrochloric acid. The data of our previous work of corrosion of mild steel and copper – nickel alloy in hydrochloric acid were taken in order to apply these methods. The parameters of these methods, such as, corrosion currents and Tafel slopes were estimated using Levenberg-Marquardt estimation method. Both methods can be used to represent the corrosion rate data with high correlation coefficient. The results were more accurate with McLaughlin equation. Keywords:- Corrosion, three point method, hydrochloric acid, metal alloys. | ||
