Design and development of scanning reference electrode technique for investigation of pitting corrosion in FV 448 gas turbine disc steel

Abstract

The scanning reference electrode technique is a recent development which enables in situ studies to be made of many forms of localised corrosion. This technique has been utilised in the design and evolution of an apparatus which can detect and monitor small potential variations associated with active pitting in FV 448 gas turbine disc steel.
