Published purpose

This Project aims to address the development and application of microelectrochemical techniques as contributors to the in-service corrosion behavior of specimens that are sensitive to filiform corrosion. The Project consists of the following 4 research areas: • Micro-electrochemical investigation of aluminum alloy samples; • Post-mortem investigation of samples following in-service exposure; • Numerical simulation of micro-electrochemical corrosion processes; and • Corrosion metrics correlation across testing scales. The Project will study a selection of 10 aluminum alloys / surface finish / conversion coating combinations to be chosen from the bank of materials available and already tested in-service at NRC. The smart selection of materials will be based on their behavior in service, the mismatches observed and the relevance of these for members of the METALTec industrial research group whose individual activities cover the entire supply chain of the automotive and surface transportation industry.
