Research:
PhD title:  Erosion-Corrosion Performance of Hardfacing Alloys

 The project investigates the erosion-corrosion performance of high chromium white iron hardfacing alloys.  The investigation centres on the role of recently discovered carbide morphologies that are expected to effect erosion-corrosion performance exposed to an environment similar to those found in the alumina refining process.  A newly developed hardfacing overlay composition, which will have minimised the undesirable carbide morphologies will be trailed for improved wear resistance.  The outcome of the investigation will be a quantitative model for the erosion-corrosion mechanism of high chromium white irons exposed simultaneously to a highly caustic, corrosive environment, and abrasive environment.
