Research Symposium

BIO

My name is Maddox Jordan, and I am a sophomore Mechanical Engineering student, as well as an honors student. I'm from St. Johns, Florida, and have really enjoyed my first research opportunity at FSU through the UROP program. Being able to work in a tribology lab has helped me to understand how the concepts I have been learning can be applied in real world applications. I hope to continue my research after the conclusion of UROP, and learn even more about the field of tribology.

Characterization of MoS2 in Extreme Environments

Abstract

Molybdenum Sulfide (MoS2) is a dry lubricant that can endure extremely low pressure. Due to its low friction properties in vacuum environments, it is used in space environments. MoS2 has potential to be used in low temperature applications, like space. To evaluate the behavior of MoS2 at lower temperatures, we tested the wear and friction of the film at 20°C and -60°C. All samples were made by sputtering MoS2 onto 440C steel substrates. Friction experiments were conducted on a custom linear reciprocating tribometer with a temperature-controlled stage. A Scanning White Light interferometer (SWLI) was used to measure the volume of material removed during an experiment. The tribological properties of MoS2 at 20°C and -60C are displayed in this poster.
