Abstract

Addition of elemental Auger spectra has been used to produced several series of Auger lineshapes versus composition for the ovelapping peaks resulting from mixtures of Cu, Pt, Pd or Ag in Au; S in Au or Pt, Cl in Au, Pt or Pd; C (both graphitic and carbidic) in Au, Pt, Ag or Pd. These assorted lineshapes series may be used to obtain semi-quantitative analysis of overlapping peaks by matching lineshapes, but have also been used to calibrate peak ratios versus composition in order to quantitatively separate contributions to overlapping Auger peaks. This procedure is illustrated by application to the quantitative analysis of tw electrical contact alloys - ASTM B541. Advantages and limitations of this procedure are B540 and ASTM B541. Advantages and limitations of this procedure are discussed.
