Focused ion beam tomography of WC-Co cemented carbides [PDF]

, 2017
The microstructure of three different grades of WC-Co cemented carbides (hardmetals) has been reconstructed in three dimensions after sequential images obtained by focused ion beam. The three dimensional microstructual parameters are compared against the

A Simplified Technique for the Fabrication of Esthetic and Functional Space Maintainers in Pediatric Dentistry

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Introduction Premature loss of primary molars remains a frequent clinical problem in pediatric dentistry and may lead to space loss, occlusal disturbances, and the need for future orthodontic intervention. Conventional space maintainers, such as the band‐and‐loop appliance, are effective in preserving arch length but do not restore occlusal ...

Influence of Airborne‐Particle Abrasion and Thermal Cycling on Enamel Bond Strength and Roughness of Lithium Disilicate Treated With a Self‐Etching Ceramic Primer

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study investigated the effect of a self‐etching ceramic primer (Monobond Etch & Prime [MEP]), with or without aluminum oxide airborne‐particle abrasion, on the surface roughness, and microtensile bond strength (μTBS) of lithium disilicate bonded to enamel, compared with the conventional hydrofluoric acid plus silane (HF

Solid-solubilities of grain-growth inhibitors in WC-Ni-based cemented carbides: experimental investigations and thermodynamic calculations

Journal of Materials Research and Technology, 2020
Cr3C2, TaC and VC are the most widely used grain growth inhibitors (GGIs) in cemented carbides. The inhibition effectiveness and the formation of brittle carbides by over-doping these GGIs are closely associated with their solubilities in the binder ...
