Behavior of dissolved molybdenum during localized corrosion of austenitic stainless steel

PDF Version Also Available for Download.

Description

An in situ study of the chemistry of molybdenum during localized of corrosion of stainless steel in chloride solutions has been carried using energy dispersive x-ray techniques. An artificial pit was used to maintained a one dimensional diffusion geometry by dissolving back the cross section of strip of Type 316 stainless steel foil mounted in an epoxy resin. A high intensity 8 {mu}m diameter polychromatic x-ray beam at Beamline x26A was scanned across the steel, a salt layer on the steel, and the concentrated dissolution products within the artificial pit. The resulting x-ray fluorescence was analyzed to determine changes in ... continued below

Description

An in situ study of the chemistry of molybdenum during localized of corrosion of stainless steel in chloride solutions has been carried using energy dispersive x-ray techniques. An artificial pit was used to maintained a one dimensional diffusion geometry by dissolving back the cross section of strip of Type 316 stainless steel foil mounted in an epoxy resin. A high intensity 8 {mu}m diameter polychromatic x-ray beam at Beamline x26A was scanned across the steel, a salt layer on the steel, and the concentrated dissolution products within the artificial pit. The resulting x-ray fluorescence was analyzed to determine changes in concentration of the constituent alloying elements. It has been found that the salt layer on the steel was formed mainly by iron chloride and all other alloying elements were present at relatively lower concentrations than n the steel. Virtually no chromium remained in the salt layer. Also, little molybdenum was present negating proposed corrosion inhibition by a definitive molybdenum forming salt layer. Within the concentrated artificial pit solution it was found that alloying elements dissolved and migrated down a concentration gradient, but closer to the mouth of deep ({approximately}2 mm) pits, precipitation of molybdenum occurred to a minor extent that did not affect the localized corrosion processes.
