Analysis of binary alloy surfaces by low wattage glow discharge emission spectrometry

The surfaces of a few binary alloys, Ag-Cu, Cu-Ni, and Ni-Co alloys, were investigated by low wattage glow discharge emission spectrometry. It was found that the characteristics of sputtering for each alloy obtained in this work corresponded to the earlier works by other techniques for surface analysis such as Auger electron spectroscopy and secondary ion mass spectrometry. This method can be extended to the study of real surfaces without ultrahigh vacuum conditions and some advantages were found comparing to the discharge at the abnormal glow region which is not low wattage in this study. 23 references, 8 figures, 3 tables
