Comparing Galvanic Corrosion Rates Predicted From Polarization Curves With Empirical Data From A Carbon Steel And Monel Couple For A Various Geometries, Michael Hinnebusch
Comparing Galvanic Corrosion Rates Predicted From Polarization Curves With Empirical Data From A Carbon Steel And Monel Couple For A Various Geometries, Michael Hinnebusch
Williams Honors College, Honors Research Projects
The objective of this investigation was to compare the galvanic corrosion rate of carbon steel C1018 and Monel K-500 alloy in a bolt and plate geometry to that derived using Tafel plots. This was achieved using carbon steels sheets of steel with a pair of with varying the number of Monel bolts and varying spacing. It was found that the carbon steel plates do not corrode uniformly. This can create issues when using Polarization curves to assume galvanic corrosion rate of a carbon steel and Monel system. The geometry of the bolts can further affect this corrosion rate and make …

Design Of Pigments For Use In “Cool” Coatings, Tyler Laughorn
Williams Honors College, Honors Research Projects
This project was focused on the development and testing of several novel pigments that exhibit high NIR-reflectance and therefore show potential for use in “cool” coatings. A “cool” coating will reflect more solar radiation than other standard coatings, and so a coated structure would require less energy to keep cool. Four sets of pigments were synthesized: Co1-xMgxCr2O4 (teal), Co0.25Mg0.75Cr2-yAlyO4 (blue), Ti1-x-yNixSbyO2 (yellow), and Cr2-xFexO3 (black). NIR and TSR values were then measured …
