Effects of porosity in a model of corrosion and passive layer growth [PDF]

, 2017
We introduce a stochastic lattice model to investigate the effects of pore formation in a passive layer grown with products of metal corrosion. It considers that an anionic species diffuses across that layer and reacts at the corrosion front (metal-oxide

Corrosion. Corrosion Rate of Thermal Sprayed WC Cermet Coating.

Journal of the Society of Materials Science, Japan, 1999
The corrosion rates of thermal sprayed WC cermet coatings in 0.05mol/dm3 sodium sulfate solutions at pH 1.0, 6.5 and 12.0 have been measured using AC impedance method and quantitative analysis of the solutions. The cermet coating films were made of WC-Co, WC-Co-Cr and WC-Cr-Ni powder matrials by the high velocity oxygen-fuel spraying method.

Is Cell Viability Always Directly Related to Corrosion Resistance of Stainless Steels? [PDF]

, 2016
It has been frequently reported that cell viability on stainless steels is improved by increasing their corrosion resistance. The question that arises is whether human cell viability is always directly related to corrosion resistance in these biostable ...

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

Advanced Functional Materials, EarlyView.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for
