Electron Diffraction: Observation of Sulfiding of Thin Cobalt Films by Means of Electron Diffraction

摘要

It was proposed that the study of gas-metallic surface interactions be resumed, producing the reaction in the interior of an electron diffractor simultaneously with sample preparation. Thin cobalt films were used. Two series of experiments were performed. In the first sulfiding took place at ambient temperature, sulfur being admitted rather suddenly onto cold, unannealed cobalt films. In the second series, heated films of annealed cobalt were used, the sulfur vapor being admitted slowly by means of a microvalve. The resulting various formations and their kinetics are described.
