Abstract

ABSTRACT Au thin films were deposited using electron beam evaporation onto the surface of Nb metal to serve as thin film markers to study the growth mechanisms of NbS2 scales. Scanning Auger microscopy (SAM) was used to measure the depth profiles for the compositions of Au, Nb, S, Si and O across the sulfide scale. Three other marker experiments were also studied. All four marker experiments indicated that the inward diffusion of sulfur is the dominant process responsible for the growth of NbS2 scales.
