A Study on Metal-Ceramic Interface on Metal Base Dental Alloys
Key Engineering Materials, 2015Although the literature describes many studies that attempt to define and interpret the interaction between the metal component and overlying sintered ceramic mass, researchers still have conflicting opinions. It is not yet fully understood the hybrid layer occurrence phenomenon that rises by diffusion at the sintering temperature between the ...

Characterization of two ceramic-base-metal alloys
The Journal of Prosthetic Dentistry, 1978Compositions, microstructures, properties, and heat treatment characteristics of two ceramic-base-metal alloys were studied. The materials displayed significant compositional and structural differences. Both alloys were strengthened by precipitation hardening.

Bonding of dental porcelain to ceramic-metal alloys
The Journal of Prosthetic Dentistry, 1987The bond strength of porcelain to the four gold alloys and the three nonprecious alloys was tested with a simplified pull test method, having wide test surfaces. The tests showed that all gold alloys tested were suitable for fusing porcelain. The bond strength in nonprecious alloys was somewhat lower and the location of the fracture lines was more ...

Fit of titanium and a base metal alloy metal-ceramic crown
The Journal of Prosthetic Dentistry, 2000Titanium has been widely used in dental implantology. However, problems remain for use of titanium in prosthodontics.This study evaluated the marginal and inner fit of metal-ceramic restorations and frameworks made with a nickel-chromium alloy (Remanium CS) and a commercially pure titanium (Rematitan).

Defect and Diffusion Forum, 2014
This study investigated actively brazing Alumina-to-Alumina with Ag-Cu-Ti as the filler metal system and Alumina-to-Copper with Cu-Ti-Co as the filler-metal system. The research was conducted on four samples, two of which were alumina brazed to alumina (Samples 1 & 2), and the other two were alumina brazed to copper (Samples 3 & 4).

Noble Metal Alloys for Metal-Ceramic Restorations
Dental Clinics of North America, 1985A review of the comparative characteristics and properties of noble metal alloys used for metal-ceramic restorations has been presented. Selection of an alloy for one's practice should be based on long-term clinical data, physical properties, esthetic potential, and laboratory data on metal-ceramic bond strength and thermal compatibility with ...

Mechanical properties of metal-ceramic alloys at high temperature
Dental Materials, 1990Four alloys used for the construction of porcelain-fused-to-metal restorations were tested at high temperatures (1000 degrees C) so that loss of properties could be ascertained. In addition, thin flat plates of metal (30 x 11 x 1 mm) with a 9-mm recess and a metal thickness of 0.35 mm were processed for porcelain application and distortion measured at ...

Metal‐Ceramic Interface Evaluation of a Gold‐Infiltrated Alloy
Journal of Prosthodontics, 2009Abstract Purpose: The success of metal‐ceramic systems partially depends on the formation of a stable bond between metal and porcelain. The purpose of this study was to investigate the porcelain/metal interface and the mechanism of interfacial bonding in a gold‐infiltrated alloy (Captek).

Micromachining of Metals, Alloys and Ceramics by Picosecond Laser Ablation
ASME 2008 International Manufacturing Science and Engineering Conference, Volume 2, 2008Microhole drilling and microstructure machining with a picosecond (ps) Nd:YVO4 laser (pulse duration of 10 ps) in metals, alloys and ceramics are reported. Blind and through microholes were drilled by percussion drilling as well as trepanning drilling. The diameters of the holes were in the range from 20 μm to 1000 μm.

Effect of pH on endotoxin affinity for metal-ceramic alloys
The Journal of Prosthetic Dentistry, 2001Crevicular pH may modify bacterial endotoxin affinity for high-noble metal-ceramic alloys.Porphyromonas gingivalis lipopolysaccharide (LPS) affinity for 3 metal-ceramic alloys at 3 different pH levels was compared in vitro by measuring adsorption to and release from the alloy surface.Metallographically polished disks were fabricated from Pd-Ag-Sn, Au ...
