INVESTIGATION OF A NEW METHOD FRO THE DETERMINATION OF THE COEFFICIENTS OF SURFACE DIFFUSION OF METALS

摘要

This report contains the results of a series of experi¬ments which were made in an attempt to_devel.o.p new methods for determining the surface diffusion coefficients of metals. The methods which were evaluated used three basically differe types of measurement, an optical method which followed the height changes of a diffusing strip using interferometric measurements, an electrolytic method which utilized a solid electrolyte to transform the mass flow of the diffusing atoms into an electric current, and an autoradiographic method which utilized photographic processes to trace the progress of the diffusing atoms
