题目: A novel electrochemical method for detection and quantification of Laves phase in 12Cr martensitic stainless steel
报告人: Jian Xu
Abstract: An electrochemical method
for the detection and quantification of Laves phase in 12Cr martensitic
stainless steel is proposed in the present work. Laves phase dissolution
peak can be observed at the lower potential range which can be obtained
in anodic polarization curves in a specific solution with specific pH
values. The amount of Laves phase was calculated by the integration of
anodic current with time according to the polarization curve and also
independently measured by using scanning electron spectroscopy. A good
correlation of these two quantifications methods was obtained.
Speaker’s Biography: Jian Xu is an assistant professor of Tohoku
University in Japan. He got his Ph.D degree in Chinese Academy of
Sciences in 2012 and worked as a post-doctor in Tohoku University until
2014. During the post-doctoral period, his research addressed issues in
the corrosion behavior of Ni based weld metals in high temperature
water, and mainly focused on the effects of water chemistry on the oxide
film and SCC of the materials using some in situ monitoring methods.
Now he is mainly involved in the development and evaluation of new
corrosion resistant alloys. From Sep. 2018 he will join Sun Yat-sen
University and build up the group of materials corrosion and protection
in extreme environments.
