| Abstract Scope |
The increasing complexity of in-situ TEM corrosion studies has mirrored the rapid growth in microfluidic TEM experiments. Over the last decade, Sandia has explored a range of in-situ TEM corrosion experiments starting with deterioration of high purity nanocrystalline metals in brine or acetic acid solutions through localized corrosion of low-carbon steel initiated at a triple junction of ferrite and cementite phases. These efforts continue with a recently developed set of microelectromechanical TEM devices to explore stress corrosion cracking and subsequently envisioned SCC experiments. The ability to perform these increasing complex in-situ TEM microfluidic experiments provides the ability to study initiation and interactions of various corrosion mechanisms with nanometer resolution. Sandia National Laboratories is a multimission laboratory managed and operated by National Technology & Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525. |
