Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

Advanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Strength and Fatigue of Silicon Nitride/Silicon Nitride and Alumina/Alumina Joints

JSME international journal. Ser. A, Mechanics and material engineering, 1994
To investigate the fatigue behavior of bonded ceramics, Si 3 N 4 /Si 3 N 4 and Al 2 O 3 /Al 2 O 3 joint specimens were three-point-fatigue-tested under static and cyclic loading at temperatures ranging from 300 to 1 038 K in air. Fractographic observation was also carried out using SEM after the fatigue test.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.
