Raman studies of tribological model systems
Abstract
The purpose of this study was to explore tribological model systems. Specifically, the types of molecular forces a chemical bond will undergo while under tribological stress. While tribology has been a growing field of interest, many of the studies have focused on the mechanical conditions while few have considered the chemical wear and tear. Tribological forces are generally mechanical in nature, but molecules undergoing these mechanical force changes are known to change their respective vibrational frequencies or break apart and form derivatives. In this study directly, molecular bonds of different types have been investigated by Raman spectroscopy under different types of shear stress. The different types of shear stress included compression, stretching, and elongation. While suggestions are given about the next step in the formation of molecular derivatives, the main thrust of the study has been to focus and explain the molecular bond changes as a function of tribological shear stress.
