中国材料名师讲坛第114讲——瑞典皇家理工学院Christofer Leygraf 教授

Christofer Leygraf, Professor em., KTH Royal Institute of Technology, Stockholm, Sweden


Atmospheric corrosion is the most costly form of corrosion with a broad spectrum of societal implications. It is probably also the most complex form of corrosion. The reason is that three phases (atmosphere, aqueous, solid) and two interfaces (atmosphere/aqueous and aqueous/solid) act simultaneously. 

To extract more basic information on the physicochemical processes that govern atmospheric corrosion it is necessary to design and study model systems, which are simple enough for fundamental studies, yet complex enough to be relevant for practical purposes and applications.  Due to international exposure programs, sophisticated laboratory experiments, developments of more advanced analytical techniques and advancements in computational modelling, our understanding of atmospheric corrosion has greatly increased [1].

This lecture within the China Distinguished Material Scientists Forum is of generic nature and will highlight advancements from recent studies in the author’s ongoing research activities in atmospheric corrosion, with a focus on copper. They include atmospheric corrosion monitoring under in situ conditions with extremely mass sensitive techniques and cases studies from macroscale to nanoscale in which, among others, direct evidence of so-called corrosion cells are presented using high-resolution analytical techniques.

During 30 years that have passed since his appointment as Professor of Corrosion Science at KTH Royal Institute of Technology in Stockholm, Sweden, Christofer Leygraf has founded and maintained a large research group that deals with a broad range of basic and applied aspects of atmospheric and aqueous corrosion. Sustainable activities have been developed to establish a more fundamental foundation of atmospheric corrosion, largely through cross-disciplinary interaction between scientists in physics, chemistry, materials science and environmental science. These efforts were recently summarized in the second edition of the book Atmospheric Corrosion (Wiley, 2016). 

Today Christofer Leygraf is Professor Emeritus at KTH. He is an elected member of the Swedish Royal Academy of Sciences and Honorary professor at the University of Science and Technology, Beijing (China). He has received a number of international awards and distinctions, including the 2003 Herbert Uhlig Award (US), 2006 Khwarizmi International Award (Iran), 2007 Willis Rodney Whitney Award (US), 2009 U.R. Evans Award (UK), 2013 European Corrosion Medal (EFC) and 2017 Marcel Pourbaix Award (ICC). He has supervised around 50 PhD-students to a doctoral degree, three of which have received the Morris Cohen Award from the Electrochemical Society, in 1996, 2007 and 2016 respectively. In international competition this Award goes to one doctoral student each year for the best doctoral thesis in the corrosion field, worldwide.
