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

Advanced 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 ...

Microstructural and Mechanical Properties of a Hard Anodic Coating Applied on an Elastically Prestrained Aluminum Substrate

Advanced Engineering Materials, EarlyView.
Prestraining the substrate influences coating formation process. Higher prestraining force leads to higher coating thickness and lower hardness. Increase in prestraining force enhances preliminary damage in hard anodic coating. Fatigue damage mechanisms change for hard anodized prestrained samples.

A facile approach to nanoarchitectured three-dimensional graphene-based Li–Mn–O composite as high-power cathodes for Li-ion batteries

Beilstein Journal of Nanotechnology, 2012
We report a facile method to prepare a nanoarchitectured lithium manganate/graphene (LMO/G) hybrid as a positive electrode for Li-ion batteries. The Mn2O3/graphene hybrid is synthesized by exfoliation of graphene sheets and deposition of Mn2O3 in a one ...

Improving Surface Quality of Titanium Electrodeposition from a Deep Eutectic Solvent with Organic and Inorganic Additives

Advanced Engineering Materials, EarlyView.
Herein, the electroplating of titanium from an organic solvent, ethaline, is shown. Polymer additives are shown to smooth the roughness of the film, and small molecule additives are shown to produce a near‐mirror finish to the deposited metal. Titanium electroreduction is desired for a variety of medical, electronic, and bonding applications but has ...
