Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

Equilibria in Electrochemistry and Maximal Rates of Reaction [PDF]

open access: yesarXiv, 2022
We consider Gibbs' definition of chemical equilibrium and connect it with dynamic equilibrium, in terms of no substance formed. We determine the activity coefficient as a function of temperature and pressure, in reactions with or without interaction of a solvent, incorporating the error terms from Raoult's Law and Henry's Law, if necessary.

Phase field modeling of electrochemistry II: Kinetics [PDF]

open access: yesPhysical Review E, 69, (2004) 021604, 2003
The kinetic behavior of a phase field model of electrochemistry is explored for advancing (electrodeposition) and receding (electrodissolution) conditions in one dimension. We described the equilibrium behavior of this model in [J. E. Guyer, W. J. Boettinger, J.A. Warren, and G. B.

Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

open access: yesAdvanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...
