Removal of casting defects from CMSX-4® and CMSX-10® alloys by electropolishing in a novel electrolyte; Deep Eutectic Solvent

Here we describe the use of environmentally benign Deep Eutectic Solvents (DESs) to electropolish oxide casting scale from Ni based superalloy turbine blades. These new electrolytes are a viable alternative to hazardous and aggressive aqueous acids and etchants currently used to process these compo...
