Auger Analysis of the Passivation of Gadolinium by Electropolishing

A method of electropolishing has been developed at the Ames Laboratory which produces a shiny surface on Gd that remains untarnished for years at 20 deg C. Auger depth profiles have revealed the presence of a Cl-bearing layer on top of the native oxide after electropolishing with a chilled methanol-...

Summary:A method of electropolishing has been developed at the Ames Laboratory which produces a shiny surface on Gd that remains untarnished for years at 20 deg C. Auger depth profiles have revealed the presence of a Cl-bearing layer on top of the native oxide after electropolishing with a chilled methanol-perchloric solution. Even though this passivating film is only a few monolayers thick it is continuous and stable for at least two years under room-temp. air exposure.--AA
