Pursuit of real contact area up to the complete contact-study on two-dimensional regular wavy surface of rubber under atmosphere and decompression environments- Reviewed

Matsuda K., Okuda Y., Nakamura K.

Toraibarojisuto/Journal of Japanese Society of Tribologists 55 ( 7 ) 509 - 517 2010.09

Language：Japanese Publishing type：Research paper (scientific journal)

The elastic contact of two-dimensional regular wavy surface with a flat surface is studied by using three types of blocks of silicone rubber as specimen. The effect of the surface profile on the growth of the real contact area is investigated from the first touch to the complete contact The experimental results show the formation of the percolation channels allowing the leakage of fluid and the dependence of the size of the contact area on the load are markedly affected by the shape of the valley of the wavy surface. In the case of the specimen with U-shaped trough, each contact spot touches the neighbors before complete contact, resulting in the extinction of the percolation channels. In this case, the real contact area linearly increases with the load if the real contact area approaches the complete contact On the other hand, in the case with V-shaped trough, the percolation channels could be hardly extinguished. The effect of the air entrapped between the contact surfaces is also discussed.

Influence of argon pressure on friction and wear characteristics in air of sputtered molybdenum disulfide films Reviewed

Matsuda K., Koguma K., Kaneta M., Ikeda M.

Toraibarojisuto/Journal of Japanese Society of Tribologists 55 ( 6 ) 406 - 412 2010.08

Language：Japanese Publishing type：Research paper (scientific journal)

Sputtered molybdenum disulfide (MoS2) films having various densities, interplanar spacing and proportion of void were prepared on the surface of the rollers for cross roller bearing by varying argon gas pressure from 1.7 Pa to 6.7 Pa. After sputtering, dry air was introduced into the vacuum chamber, and then the rollers were exposed in air atmosphere. The effect of the introduction of dry air into the vacuum chamber on the friction and the wear life of the MoS2 films have been investigated by the friction test conducted in air atmosphere where the humidity is controlled. It is found that the effect of the introduction of dry air into the vacuum chamber varies depending on the argon gas pressure. The film prepared by an argon gas pressure of 4.0 Pa, which has a higher true density and a lower (00·2) interplanar spacing, shows the most significant improvement of the tribological performance. It is also found that even a 4.0 Pa film shows a sharp drop of wear life when storage period of the test piece in air of 30% relative humidity exceeds 50 days.
