A rotating disk study of impurity segregation in aluminum alloy solidification
… intermetallic compounds. A small-scale rotating disk experimental approach was used to study the segregation of iron, the most common impurity in aluminum alloys, in the presence of forced convection. Applying forced convection was found to deplete iron from solidified aluminum, and …

Rotating Disk Electrode Design for Concentration Measurements in Flowing Molten Chloride Salts
… this study attempts to understand. Two different rotating electrodes were designed to simulate flowing conditions in an electrochemical cell. The first was a tungsten rotating disk electrode (RDE) and the second was a graphite RDE. We were not able to fully insulate the tungsten RDE and were …

On the reduction of oxygen from dispersed media
… Oxygen was reduced from the emulsion on a rotating disk electrode. The dispersed phase did not contribute to the oxygen transport to the surface of a rotating disk electrode. An explanation is given based on the hydrodynamics of an emulsion under a rotating disk electrode. To eliminate the …
