Potentiodynamic study was carried out on nickel in Na2SO4 solution in the presence of ClO4–, WO42–, MoO42–, NO2– and NO3– ions. The anodic excursion spans of the metal nickel in a solution of Na2SO4 are marked by the appearance of clearly defined anodic peak, passive region, and transpassive shoulder. According to the data, the anodic peak current density (IPAI) rise from 1.82 to 8.12 mA cm–2 as the concentration of the Na2SO4 solution rises from 0.2 to 1.0 M. It is clear that as scan rate increases, the IPAI rises reaching to 11.8 mA cm–2. The apparent activation energy of nickel corrosion in Na2SO4 is 33.25 kJ mol–1. ClO4– anion addition speeds up nickel’s active dissolution, as well tends to break down the passive layer, and causes pitting penetration. It was found that, the pitting potential (Epit) of nickel in solutions containing the two anions ClO4– and SO42– shifts to the positive direction by addition of WO42–, MoO42–, NO2– anions and shifts to the negative direction by addition NO3- anion. Epit increased by 0.67, 0.37 and 0.15 V in the presence of WO42–, MoO42– and NO2–, respectively. WO42– > MoO42– > NO2– was the order in which the inhibitors were most effective.

The rising cases of corrosion problems in pipelines, refineries, water treatment and petrochemical plants, as well as in power generation plants in recent time have been attributed to industrialization. The longevity and dependability of essential assets must be ensured through effective corrosion management. The various techniques applied for corrosion protection are discussed in this review. But in recent years, the development of response surface methods (RSM) and artificial neural networks (ANN) has shown exciting prospects to transform the corrosion monitoring process. This review paper gives a thorough overview of corrosion optimisation strategies. The role of ANN and RSM in predicting corrosion using various parameters is discussed. By providing insights into the current state of research on ANN, this paper aims to promote a deeper understanding. The review emphasises how crucial it is to adequately manage corrosion if essential assets are to last a long time and function consistently.
