Application-Focused Corrosion Research

Abstract This chapter provides an overview of major corrosion testing and analysis techniques and their applications in corrosion inhibitor research, with a particular focus on electrochemical evaluation of corrosion protection by rare earth metal (REM) compounds. Attempts are made to discuss fundamental issues in inhibitor test design such as limitations in corrosion measurement techniques and challenges that may lead to the reporting of inaccurate corrosion rates and patterns. 

Since the 1980s the rare earths have been the subject of intensive research in corrosion science. The pioneering work of Amott, Hinton and co-woikers demonstrated that rare earth chlorides imparted considerable corrosion protection to a number of metals under iimnersion conditions in chloride-containing electrolytes. Since that time rare earths have been considered for deoxidisers " and conversion coatings in aerospace and architectural A1 finishing and in inhibited paint systems."" In addition to these application-focused studies, there have been many other studies examining the more fundamental aspects of rare earth inhibition on many metals. ...
