Abstract:

This research presents results of the experimental study and analysis of corrosion within Wolverine. Corrosion on the surfaces and its propagation into sub-surface was analysed. Surface corrosion was observed and propagated almost 250 µm deep in to the sub-surface. Iron (Fe) was oxidised to 52.66 wt % at one spectrum on the corroding surface. A cross-sectional materials’ characterisation study of the selected samples showed that manganese (Mn) based steel has been deployed in the manufacture of the specific part. Environmental and dilute cyclic salt fog corrosion experiments were simulated to inform remaining life assessment techniques. Results from simulated environmental tests have shown corrosion accumulation on the surfaces and corrosion build-up was relatively more at the edges. Experimental results of the same samples subjected to cyclic salt fog tests have shown 100% corrosion build-up within 48 hours of exposure time. The relationship of various temperatures and relative humidity with respect to time, within the context of corrosion initiation and propagation, has been studied to evaluate quantitative corrosion damage to structures of military tanks. The current research investigation is to draw a sustainable environmental framework to diminish or at least decelerate corrosion in the museum environment.
