Abstract
The objective of this study was to examine the wear-corrosion behavior of 18Mn(V, Mo) steel, which had a minor amount of Cr addition (< 3 wt%), in an artificial seawater environment, and compare it to conventional carbon steel. A variety of electrochemical experiments, including linear polarization resistance, impedance spectroscopy, and..... More

DOI: https://doi.org/10.3365/KJMM.2019.57.10.624

Abstract
High-Mn steels developed for offshore industries require good resistance to stress corrosion cracking (SCC) in seawater. Elements like Cr and N are often added to improve the resistance to SCC. In this study, the SCC behavior of Fe18Mn3Cr0.1N and Fe19Mn19Cr0.6N steels in artificial seawater was examined. Slow strain rate tests..... More

Korean J. Met. Mater. 2017;55(8):591-599.   Published online 2017 Aug 1
DOI: https://doi.org/10.3365/KJMM.2017.55.8.591

Abstract
In this paper, the influence of mixed-type (impressed-current and sacrificial-anode) cathodic protection on an underwater electromagnetic field was investigated using the boundary element method. The current applied for cathodic protection was reduced by installing sacrificial anodes in the stern region. Also, the potential difference produced by the propeller in the..... More
