New research examines corrosion on atomic level

Posted by in categories: chemistry, engineering

When water vapor meets metal, the resulting corrosion can lead to mechanical problems that harm a machine’s performance. Through a process called passivation, it also can form a thin inert layer that acts as a barrier against further deterioration.

Either way, the exact chemical reaction is not well understood on an , but that is changing thanks to a technique called environmental transmission electron microscopy (TEM), which allows researchers to directly view molecules interacting on the tiniest possible scale.

Professor Guangwen Zhou—a faculty member at Binghamton University’s Thomas J. Watson College of Engineering and Applied Science—has been probing the secrets of atomic reactions since joining the Department of Mechanical Engineering in 2007. Along with collaborators from the University of Pittsburgh and the Brookhaven National Laboratory, he has studied the structural and functional properties of metals and the process of making “green” steel.
