M.Tech. (Engineering: Metallurgy) / The aim of the study was to determine the slurry erosion-corrosion rates as well as electrochemical corrosion rates of WC-Fe-Ru coatings that were thermally coated using a plasma transferred arc method. The WC-Fe-Ru coatings used had different bulk Ru concentrations that varied from 0.7 to 4.1 wt% Ru. A slurry jet impingement erosion-corrosion test rig was used for the erosion-corrosion rate measurements, and an Autolab 302 potentiostat was used to measure the open circuit potential during a 12 hour exposure in the test solution, as well as a potentiodynamic scan to determine the corrosion potential...
