SEM/EDS of Al Corrosion Samples


EMSL Project ID
1806

Abstract

This work supports the DOE-BES funded program entitled Fundamental Studies of Stress Corrosion Cracking, managed by Russ Jones at PNNL. Collaborators include other PNNL staff members: Don Baer (EMSL), Mark Engelhard (EMSL), Mike Danielson (326 Bldg.), and John Vetrano (326 Bldg.). The objective of this program is to determine the mechanisms of cracking for metals in various environments. Currently we are interested in aluminum. The SEM/EDS work will help identify the morphology and composition of corrosion products on samples generated in PSL laboratories and generated/analyzed using the Quantum 2000 XPS system with corrosion cell in EMSL. The XPS studies have been in progress for several years. Recent results suggest that SEM/EDS may be helpful in interpreting some of the spectroscopic results. The samples should pose no unusual problems/requirements for SEM/EDS analysis.
