| Research Abstract |
To evaluate the friction characteristics of monolayer liquid lubricant (molecularly thin lubricant film), the surface of sliding pins were super-smoothened with the gas cluster ion beam (GCIB) processing to have a surface roughness less than the lubricant thickness, and a novel sliding pin assembly comprised of a sliding pin, a suspension and a double-leaf parallel spring (deflection sensor) was developed which had an advantage of suppressed friction-induced vibration. In addition, friction tests were performed for nanometer thick lubricant films coated on the magnetic disk surface, which showed good availability of the newly develop sliding pin assembly for evaluating the friction characteristic of molecularly thin lubricant films.
