A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?

Advanced Engineering Materials, EarlyView.
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Partitioning and Coarsening Dynamics of Precipitate‐Strengthened Cr‐Si Alloys: The Role of Ge, Pt, and Mo

Advanced Engineering Materials, EarlyView.
The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.

Development of a Novel Processing Route for Dispersoid/Precipitation‐Strengthened High Conductive Copper Alloys by Using Metalized Nanoceramics in Additive Manufacturing

Advanced Engineering Materials, EarlyView.
This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.
