TRP 18. Corrosion Mechanisms and Kinetics of Steels in Lead-Bismuth Eutectic
May 2004 - Current
Research Objectives & Methods
The overall goal is to obtain scientific insight into the fundamental processes involved in the corrosion of steel by LBE. The experimental methods include characterization of steel samples before and after exposure to LBE using different techniques including: Scanning Electron Microscopy (SEM), Energy Dispersive X-ray analysis (EDX), Wavelength Dispersed X-ray (WDX), X-ray Photoelectron Spectrometry (XPS), Sputter Depth Profiling (SDP), X-ray Diffraction (XRD) and laser microRaman spectroscopy. These techniques have been previously used by this research group to probe the effect of surface preparation on corrosion-resistance of samples with the same chemical composition, and to examine the role of silicon in silicon-containing steel.
During the past year, gas-phase experiments were conducted in which steel samples were oxidized in glass capsules at elevated temperatures in a tube furnace. Corroded steel samples were analyzed from a variety of sources, including the Delta loop at LANL and samples corroded at UNLV in the gas phase experiments.
