The use of zinc and zinc alloys with additions of magnesium and/or aluminium to coat steel wire is a common and efficient method to protect the steel from corrosion. Even with these coatings applied rapid corrosion of the zinc layer can occur in aggressive environments or due to poor storage conditions, for which additional protection can be applied to the coating surface. The most successful inhibitors for such a task are those based on chromates, however their use is rapidly being reduced due to its adverse effects on health and thus alternative, safe inhibitors need to be found. The project is being undertaken as part of the ARC Research Hub for Australian Steel Innovation and will involve working with our industry partner. This research is partially funded by the Australian Government through the Australian Research Council.
This project will investigate benign inhibitor systems that synergise with the underlying alloy and/or an organic top coating for enhanced corrosion protection. A range of inhibitor types will be investigated using typical corrosion assessment techniques such as polarisation and impedance spectroscopy. As these inhibitors are being applied to minimise corrosion of the overlay, these traditional test methods will be able to quickly assess the different inhibitors. Additionally, localised electrochemical methods, such as scanning electrochemical cell microscopy, and advanced characterisation methods, such as X-ray photoelectron spectroscopy (XPS) and Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), will be used to investigate inhibition mechanisms.
