Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

Advanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Calculations of effective atomic number

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007
We will present and discuss effective atomic number (Zeff) obtained by different methods of calculations. There is no unique relation between computed values. This observation led us to the conclusion that any Zeff is valid only for given process. We will compare Zeff obtained by following methods: 1. Variational method (Slater), 2.

The effective atomic number of mix D

The British Journal of Radiology, 1979
It is well known that mix D, which was introduced by Jones and Raine (1949), has been widely used as a phantom material for photons and electrons in radiotherapy. By adding fillers of magnesium oxide and tianium dioxide to wax, they made an improvement for mix D compared with wax alone in terms of mechanical properties and the attenuation ...
