タイトル(掲載誌)航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-903
一般注記An RF sputtering apparatus with a pair of targets has been developed for depositing a film of uniform thickness onto a complex-geometric specimen such as the retainer of a ball bearing. The deposition characteristics of the apparatus were compared with those of the conventional sputtering apparatus. Lubrication properties of MoS2 films made by these devices were also compared under a variety of conditions. Finally, friction and wear of MoS2 films applied to angular-contact type ball bearings of 20 mm bore were studied in air, nitrogen and vacuo. The two-target sputtering has an advantage mentioned above, however, the films deposited by the method exhibited a rather short wear life because of the temperature rise of the substrate during ion bombardment and during the sputtering process. This temperature dependence was observed in films on those substrates that had been heated with a built-in heater during sputtering. The film thickness measurement and the observation by a SEM showed this was attributed to the porous growth of films. Thus substrates should be kept at low temperatrues when one wants to obtain an MoS2 film of high quality. As a whole, sputtered MoS2 films are an excellent lubricant under sliding contact as well as rolling contact conditions in regard to friction force and endurance life.
