Spatial Delineation Of Corrosion Zones For Metal Culverts Based On Coastal Louisiana Soil Characteristics, Sanjay Tewari, Francis Manning
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Corrosion of metal pipes used as culverts is a problem that affect many agencies directly involved in designing and maintaining these culverts. The corrosive environment of soil types found in a region could vary in a significant way (mildly corrosive to extremely corrosive) based on soil characteristics. Environmental conditions such as high water table, acidity and presence of various salts could make a soil corrosive to metal pipes. In this article, authors have applied a methodology of processing readily available soil data such as spatial distribution of soil types and soil characteristics (e.g. pH and conductivity) in delineating spatial corrosion …
Corrosion Performance Of Zirconium-Based Passivations On Electroplated Zinc Nickel, Madison Morgan Reed
Corrosion Performance Of Zirconium-Based Passivations On Electroplated Zinc Nickel, Madison Morgan Reed
Masters Theses
“Performance requirements for Department of Defense (DoD) electrical components include corrosion and electrical contact resistance. Historically, electroplated cadmium with a chromate conversion coating (CrCC) has been used to meet corrosion and contact resistance standards. However, replacements are needed for these materials because they are toxic and carcinogenic. Electroplated γ-ZnNi has been identified as an acceptable alternative to Cd. This study evaluated commercially available Zr-based thin films and sealers as passivations for potential replacement of CrCCs. Ten different passivations were tested and compared with bare γ-ZnNi. X-Bond and Zircobond passivations were found to provide some improvement to the bare ZnNi corrosion …
