- Abstract
My paper shows a study on change in tribological properties, surface micro roughness, structure and so on of lubricative coating films of TiN, Cu, Cu/BN that have been effected by exposure to an environment in orbit with the Russian Service Module / Space Environment Exposure Device (SM/SEED) prepared by JAXA on the International Space Station (ISS). It was found that substrates with exposure to orbit environment for a year generally decrease friction coefficient and can keep almost constant even after bakeout under a high vacuum as well as in an atmospheric pressure due to some kind of modification of lubricant layer by the exposure.
