ASTM E-42 ILA# 863 Round Robin Participant "XPS depth profiling of stainless steel coupons"
EMSL Project ID
48071
Abstract
This ASTM E42 round robin will explore the efficacy of using the “Bulk Ratio (BR)” method for XPS depth profiling stainless steel. The advantage of the BR method is that no calibration standards are required. After the data are collected and placed in a spread sheet, the observed intensity ratios for Fe, Cr, and Ni (Si and Mo are optional) are processed such that the ratio of Cr/Fe in the bulk (under the surface treated layer) are unity. Please see the attached technical paper describing the technique for Auger (JVST Geller, Bulk Ratio). In this standard, the method will be developed using XPS rather than Auger.
