Abstract

The work aims to simulate the galvanic corrosion behavior of 20# steel/TA2 through the comprehensive simulation pipeline platform to provide a theoretical basis for the corrosion control of seawater pipeline through-hull components. The galvanic potential and current density of couples in seawater at different flow rates within a simulated pipeline platform were measured. Additionally, SEMm, 3DVM and XRD were employed to analyze the morphology and composition of corrosion products on the surface of the couples. By integrating these findings, the mechanisms underlying galvanic corrosion were explored. The results indicated that in static seawater, the galvanic corrosion rate of 20# steel was only 0.171 mm/a; In flowing seawater, the rate of galvanic corrosion significantly increased due to the enhanced diffusion rates of dissolved oxygen and Cl^-. In seawater with a flow rate ranging from 1 to 5 m/s, the galvanic corrosion rate of 20# steel/TA2 increased by 20 to 30 times, and the galvanic corrosion rate rose with the increase of the flow rate. Due to the significant increase in the galvanic corrosion rate between 20# steel and TA2 when exposed to flowing seawater, it is essential to employ electrical insulation techniques to prevent the formation of a galvanic couple between the two materials. Alternatively, cathodic protection methods can be utilized for safeguarding purposes.
