The 8th International Symposium on Marine Corrosion and Control was held from 6/22 – 6/25 in Hokkaido University in Japan. The aim of this symposium is to provide a forum for discussion on a variety of approaches to the understanding of marine corrosion phenomena. This time the topics were focused on the corrosion and corrosion protection in marine environments from a fundamental and practical point of view.
Experts from more than 20 universities or institutes including USTB(University of Science and Technology Beijing), TIT(Tokyo Institute of Technology, NIMS(National institute for Material Science), HU(Hokkaido University) etc. attended this symposium. The presented topic covered mainly on Microbiological induced corrosion, Stress corrosion cracking and corrosion fatigue, Corrosion monitoring, electrochemical impedance and noise.
Many latest research results on marine corrosion and control were reported in the meeting. Prof. Zhang Dun from IOCAS introduced the new result of “sulphate-reducing bacteria induced Q235 carbon steel corrosion in seawater”. As the group leader of corrosion, Prof. Atsushi Nishikata reported the new discovery on” degradation of Zn-coated steel in marine atmosphere”. Prof. Wu Junsheng, an expert of TEM characterization, presented the result of corrosion behavior of nanosized copper electrode in aqueous solutions using TEM observation.
After the presentation sessions, attenders also visited the graduate school of Engineering Hokkaido University. More than 50 research groups work in this graduate school on many advanced topics. As Sapporo affords the cold climate and with heavy snow for almost half a year, the corrosion environment of both atmosphere and seawater is special. HU and NIMS founded a project and built a corrosion experiment outdoor field. Attenders inspected this filed and observed many metal sample set on the frames. After the meeting, attenders paid a visit to the seashore area of Otaru city, which was the most important port in old time. Both the seashore facilities and the city public facilities have good corrosion protection. However, many small components is seriously corroded because of long-term use. Japan government and many companies has new policy on this troubles as introduced by HU researchers.
