Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

In studies of the effect of erosion-corrosion in aqueous conditions, impact angle effects are frequently ignored. This is despite the fact that erosion has a function of impact angle and can vary frequently depending on the nature of particle/target interactions. In such cases, the impact angle effects may change depending on whether the eroding particle encounters a metallic surface or an oxide film. This work describes extension of a model already developed for erosion-corrosion of Fe to a range of pure metals, Ni, Cu, and Al at a range of pHs. The impact angle effects were estimated based on models from the solid particle erosion literature. The corrosion stability regimes were identified using Pourbaix diagrams for various pure metals. The results were used to generate erosion-corrosion mechanism maps showing the differences in the impact angle effects at various pHs for the pure metals. The changes in wastage regime for the various pure metals as a function of impact angle and pH were demonstrated. Materials performance maps were generated using such models showing how wastage rates may be optimised for exposure to impact angle, pH and electrochemical potential.
