... as dry argon, the friction coefficient was allowed to run-in to a low value, and then the amount of water vapor was ramped up and back down to see how the friction coefficient responded to these changes in relative humidity (RH) (this is plotted in Fig. 4 ). This experiment clearly demonstrated...

...Shuyu Zhang; Brian Strom; Sung-Chang Lee; George Tyndall For a hard disk drive operating in a humid environment, the water vapor in the slider’s air bearing is typically compressed beyond its saturation vapor pressure, causing the vapor to condense. Consequently, the air bearing pressure decreases...

.... The same trends hold for changes in relative humidity. Eq. (1 a ) is the general form for plane stress. This is the form used for off-axis loading. In an off-axis loading, the loads are applied at an oblique angle to the “fibers” of the composite. While magnetic tapes do not actually have “fibers...

...P. M. McGuiggan; S. M. Hsu; W. Fong; D. Bogy; C. S. Bhatia The friction force as a function of humidity was measured between thin carbon films coated onto mica surfaces. The friction force was found to be proportional to the area of contact. The shear stress at 0 percent, 33 percent, and 100...
