Friction Bearings

The influence of technological deviations on the performance of fluid friction bearings is considered. A mathematical model of a hydrodynamic sliding bearing is presented, based on a joint numerical solution of the Reynolds equation and additional relations to take into account the microroughness of the bearing surfaces. Analysis of the numerical results made it possible to assess the effect of roughness on the bearing capacity, consumption and energy characteristics of fluid friction bearings.

Deposition Techniques

Topographic ultra high resolution can now routinely be established on bulk samples in cold field emission scanning electron microscopy with a second generation of microscopes (FSEM) designed to provide 0.5 nm probe diameters. If such small probes are used for high magnification imaging, topographic contrast is so high that remarkably fine details can be imaged on 2DMSO/osmium-impregnated specimens at ribosome surfaces even without a metal coating. On TCH/osmium-impregnated specimens topographic resolution can be increased further if the SE-I imaging mode is applied. This requires that beam diameter and metal coating thickness be made smaller than the SE range of ~1 nm and background signal contributions be reduced. Subnanometer small probes can be obtained (only) at high accelerating voltages. Subnanometer thin continuous metal films can be produced under the following conditions: self-shadowing effect between metal atoms must be reduced through appropriate deposition techniques and surface mobility of metal atoms must be diminished through high energy sputtering and/or specimen cooling.
