Research Interests:
My work focuses on the tribology of ultrahard carbon films with extreme properties. These films are excellent solid lubricant candidates for a wide variety of needs, but their environmental sensitivity hinders their ready use. Depending on the exact chemistry and structure of the film, exposure to inert or reactive environments can have an almost completely polar effect on their performance.
My main effort has been in carefully performing self-mated tribometry experiments with these films in environments with a controlled level of relative humidity (RH). Changing the RH level will change the tribological behavior of the film (e.g. reducing the humidity can increase the friction and wear, for some films). Then these wear scars are carefully examined to detect both mechanical and chemical changes caused by wear.
