Paper presented at the The 32nd International Ocean and Polar Engineering Conference, June 5–10, 2022
Paper Number: ISOPE-I-22-140
.... It was noted that variations in operating conditions can influence the corrosion rate, requiring additional analyzes in the evaluation of structural reliability. As a result of the probability of failure calculation, at low operating pressure levels, the depth of the uniform corrosion does not play...

... Abstract This paper presents results from AC corrosion tests on 25Cr duplex and cathodically protected carbon steel. The results show that the corrosion rate is independent of transfer current density (0–200 A/m 2 ) and power frequency (50-200 Hz) on cathodically protected carbon steel...

...). Almusallam (2011) obtained the corroded rebar by means of electrochemically-accelerated corrosion. Wang (2003) believed that the mechanical properties of corroded rebar will decline with the increase of corrosion rate of rebar through the tensile test on rebar in reinforced concrete members that have been...

... that the corrosion rate is independent of transfer current density (0- 400 A/m2) and power frequency (0-200 Hz) on steel. On the anodes, the corrosion rate increases as a function of transfer current density (0- 80 A/m2) at 50 Hz. However, the correlation is less prominent at higher frequencies (100-200 Hz). KEY...
