Assessing Altered Coating Adhesion on Plasma‐Deoxidized Surfaces Under Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates the effectiveness of atmospheric pressure plasma pretreatment in modifying silicon and stainless steel surfaces to improve adhesion. Argon‐hydrogen plasma increases surface roughness and improves adhesion strength, whereas pure argon results in smoother surfaces and structural changes.

Simulation of cold compaction densification behavior of silicon nitride ceramic powder

open access: yes, 2019
The cold-compaction densification behavior of silicon nitride (Si3N4) ceramic powder was analyzed using two models: the Shima model and the Cam-Clay model. Triaxial-compression experimental data were used to evaluate these two models.

Nonthermal Plasma Reduction of Nickel Oxide Layers by Atmospheric Pressure Dielectric Barrier Discharge in Argon/Hydrogen

open access: yesAdvanced Engineering Materials, EarlyView.
This work explores the reduction of nickel oxide layers using dielectric barrier discharge plasma in an argon–hydrogen atmosphere. The results reveal a strong temperature dependence, enabling complete reduction of thick oxide layers at 200°C within seconds.

Fracture and interfacial delamination origins of bilayer ceramic composites for dental restorations

open access: yes, 2010
Alumina and zirconia (Y-TZP) based bilayer ceramic dental composites with core to veneer thickness ratio (R-value) of 1: 1 and 2:1 were fabricated through an established dental laboratory multi-steps-firing procedure.

Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Hard glass-ceramic coating by microwave processing

open access: yes, 2008
Microwave processing was employed in the present work to obtain hard glass-ceramic coating on nickel based superalloy substrate. The glass-ceramic coatings were developed from a glass based on MgO-Al2O3-TiO2 system.

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Photocatalityc activity of ceramics containing TiO2 powders

open access: yes, 2005
In recent years, titanium dioxide has been extensively applied in several fields, in fact it has been used in pigments, in gas sensors, in cosmetic products, in dielectric materials and for photocatalysis.
