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
(1999-03-01)
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
(2017-12-15)
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 ...
Si3N4 ceramic cutting tool sintered with CeO2 and Al2O3 additives with AlCrN coating
(ABM, ABC, ABPol, 2011-12-01)
Ceramic cutting tools are showing a growing market perspective in terms of application on machining operations due to their high hardness, wear resistance, and machining without a cutting fluid, therefore are good candidates ...
Use of Industrial Waste to Produce Ceramic Coatings on Metal
(European Center Sustainable Development, 2019-01-01)
Industrial processes are activities that produce large amounts of wastes. Often these wastes are disposed in dam or landfills, occupying large areas and causing environmental damage such as the contamination of water and ...
Piezoelectric effect in composite polyurethane-ferroelectric ceramics
(1999-03-01)
Flexible and free-standing films of piezoelectric composites made up of lead zirconate titanate (PZT) ceramic powder dispersed in a castor oil-based polyurethane (PU) matrix were obtained by spin coating and characterized ...
Silica coating on alumina ceramic: comparison of three chairside air-abrasion devices working for different times and distances.
(2011-03-01)
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
(2008-11-01)
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
(Elsevier, 2016-02)
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. ...
The effect of ceramic surface treatment on bonding to densely sintered alumina ceramic
(Elsevier B.V., 2005-03-01)
Statement of problem. Ceramic surface treatment is crucial for bonding to resin. High crystalline ceramics are poorly conditioned using traditional procedures.Purpose. The purpose of this study was to evaluate the effect ...
