Abstract
A significant portion of the global cost of corrosion originates from offshore applications, where materials are in contact with seawater. For a wide variety of applications, construction steel grade A, is used, although it is highly vulnerable to this marine environment. So far, the strategies to assess corrosion degradation, mostly focus on the ongoing corrosion and do not sufficiently address the future corrosion risk. Therefore, a more innovative and effective approach for this type of degradation is insitu monitoring of the affecting environmental parameters on the corrosion rate to determine the potential risk. Consequently, the current study aims to investigate how environmental variables such as, temperature, pH, conductivity, and salinity can influence the corrosion rate in a controlled lab environment. For this purpose, Linear polarization resistance (LPR) on grade A steel was performed for a few days using Gamry instruments’ potentiostat in artificial seawater, which was prepared based on ASTM Standard D1141. Environmental parameters were simultaneously monitored by water quality sensors. The influence of pH on corrosion rate is further investigated in light of the possible protectiveness of corrosion products/films. Furthermore, the corrosion products’ formation rate can differ and consequently influence the corrosion reaction kinetics
