Graded plasma spraying of premixed metal-ceramic powders on metallic substrates
(Asm InternationalMaterials Park, 1997)
Ceramic coating for refractories protection against carbon oxidation, Part 1: Protection mechanisms
For retarding carbon oxidation in refractories during the preheating of metallurgical furnaces, a ceramic coating, made mainly of sodium phosphosilicate and clay was developed. The coating presents high adherence to the ...
Deposition of graded SiO2/SiC coatings using high-velocity solution plasma spray
Carbon/carbon (C/C) composites are widely used in structural components, particularly in the aerospace and aeronautics sectors. However, the application of C/C composites is limited by low oxidation resistance at high ...
Silica coating on alumina ceramic: comparison of three chairside air-abrasion devices working for different times and distances.
This study evaluated, by scanning electron microscope (SEM) and EDS, the effect of different strategies for silica coating (sandblasters, time and distance) of a glass-infiltrated ceramic (In-Ceram Alumina). Forty-one ...
Adherence of Streptococcus mutans to uncoated and saliva-coated glass-ceramics and composites
This study sought to investigate the surface roughness and the adherence of Streptococcus mutans (in the presence and absence of saliva) to ceramics and composites. The early dental biofilms formed in situ on the materials ...
Processing of ZrO2 scaffolds coated by glass-ceramic derived from 45S5 bioglass
Three dimensional, highly porous, ZrO2 scaffolds coated by glass-ceramic derived from 45S5 bioglass were fabricated. The surface reactivity of 45S5 in aqueous solution was investigated as a function of the immersion time. ...
Bond strength of a resin cement to high-alumina and zirconia-reinforced ceramics: The effect of surface conditioning
Purpose: The aim of this study was to evaluate the effect of two surface conditioning methods on the microtensile bond strength of a resin cement to three high-strength core ceramics: high alumina-based (In-Ceram Alumina, ...
