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

Local Dielectric Spectroscopy of Nanocomposite Materials Interfaces [PDF]

, 2009
Local dielectric spectroscopy is performed to study how relaxation dynamics of a poly-vinyl-acetate ultra-thin film is influenced by inorganic nano-inclusions of a layered silicate (montmorillonite). Dielectric loss spectra are measured by electrostatic force microscopy in the frequency-modulation mode in ambient air.

High‐Rate Deposition and Characterization Study of CoZrO Films for On‐Chip Power Applications

Advanced Engineering Materials, EarlyView.
This study introduces a high‐rate reactive sputtering process for CoZrO films, aimed at large‐scale production of on‐chip magnetic components compatible with complementary metal oxide semiconductor (CMOS) fabrication. Characterization of the deposited films reveals that ideal magnetic properties require chemical compositions in a narrow Co:O range and ...
