Fundamental Investigations of the Surface Chemistry and Tribology of Metal Carbides and Metal Nitrides
Abstract
This research program entailed the investigation of the surface chemical and tribological (friction, lubrication, and wear) properties of titanium carbide (TiC), titanium nitride (TiN), and vanadium carbide (VC). These hard coating materials are potentially useful in enhancing the performance and extending the lifetime of lubricated spacecraft mechanisms. The program sought to establish the fundamental chemical and tribological properties of interfaces involving these materials and to understand the origin of differences between the materials, such that they may be specified and employed in DOD spacecraft mechanisms. The objective of the research was to establish a systematic understanding of the reactivity and friction of model metal carbide interfaces in terms of both the inherent properties of each material as well as the fundamental origin of differences between the materials. This objective was met by providing a base level of fundamental information regarding the chemical and tribological properties of these materials. It is envisioned that this information will allow the intelligent design of and selection of materials in future USAF satellite mechanisms.
