Plasma Nitriding of Titanium Alloys

, 2016
Titanium alloys are found in many applications where weight saving, strength, corrosion resistance, and biocompatibility are important design priorities. However, their poor tri‐ bological behavior is a major drawback, and many surface engineering processes have been developed to enhance wear in titanium alloys such as nitriding.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

The Impact of Nitriding Parameters on Evolution of Properties of Stainless-Steel Surface Plasma-Nitrided in Glow Discharge

Успехи физики металлов
Plasma nitriding in a glow discharge is a relatively new and extremely promising method of steel surface hardening. Ion-nitrided samples show a tendency to a longer lifespan during severe wear and cyclic loading compared to the traditional gas nitriding.
