The goal of this project was to study
the interface between eutectic lead bismuth (ePbBi) and epoxy in order
to get a closer look at the oxide layer forming near the
interface. By taking EDAX spectrum, it seems that the relative
concentration of oxygen is greater at the interface than that on the
bulk of the sample. The increased oxygen concentration near the
interface provides a hint that moisture and adsorbed contaminant might
be driving the oxidation near the interface.
I would like to thank
Brian McIntyre for his unique method of teaching and good humor. I would also
like to thank Douglas Kelley for the valuable discussions and for providing the necessary samples.
