Titanium-porcelain system. Part II. Bond strength of fired porcelain on nitrided pure titanium
Bio-Medical Materials and Engineering, 1997Commercially pure titanium (CPT) substrate was subjected to porcelain firing and bond strengths under three-point bending mode (span length: 15 mm; crosshead speed: 0.5 mm/min) were evaluated. Experimental variables included surface treatments of CPT and porcelain firing schedules.

The bonding strength of porcelains to metals depends on the oxide layer between the porcelain and the metal. Oxidation of a metal surface increases the bonding strength, whereas excessive oxidation decreases it. Titanium and its alloys are gaining acceptance for dental use since they exhibit excellent biocompatibility, corrosion resistance, low ...

FIRE HAZARDS ASSOCIATED WITH THE USE OF TITANIUM IN AIRCRAFT
1964Abstract : Historically, titanium and its alloys have been proven capable of performing efficiently and satisfactorily in both airframe and aircraft gas-turbine engines. Nevertheless, under certain conditions, titanium and its alloys are known to be capable of ignition and combustion.

Fast-fired, nanograined titanium niobate (TiNb2O7) with enhanced dielectric properties
Materials Science and Engineering: B, 2020Abstract The interfacial polarization, the degree of densification and the grain size are factors that directly influence the materials dielectric properties. This investigation show that is possible to tailor macrostructure and dielectrical features through sintering at high heating rates. Fast firing (FF) hinders grain growth while maintaining high

This study evaluated: (1) the marginal fit of copings fabricated from commercially pure titanium (cp Ti) and titanium-aluminum-vanadium alloy (Ti-6Al-4V) after each firing cycle for a recommended porcelain; and (2) the effectiveness of a stress-relieving treatment on the fit. The results were compared with copings made with Pd-Ag alloy submitted to the

Fire hazard of titanium powder layers mixed with inert nano TiO2 powder
Journal of Hazardous Materials, 2018Metallic dust layers are highly sensitive to ignition from common ignition sources, even when mixed with high percentages of inert solids. In turn, dust layer fires are a potential ignition source for dust explosions or other damaging fires. Flame spread velocity (FSV), as a potential parameter for evaluating fire hazard, was investigated for titanium ...

Analysis of titanium/carbon steel heat exchanger fire
Plant/Operations Progress, 1992Abstract In the past fifteen years two serious titanium fires have occurred at scrap dealer facilities. Both incidents involved the cutting of titanium/carbon steel heat exchangers by scrap metal dealers. This paper reviews the properties of titanium and carbon steel under extreme conditions and the oxy‐acetylene cutting process ...

Chromatic behavior of porcelain fired on titanium.
Quintessence international (Berlin, Germany : 1985), 2007To investigate the chromatic changes of 3 porcelains after firing on titanium.Thirty-six veneer crowns were obtained by firing 3 different porcelains to titanium: Ti22 (Noritake), Triceram (Esprident), and Vitatitankeramik (Vita). A single shade was used for each porcelain.

The aim of the study was to evaluate the effect of simulated porcelain firing cycles and surface finishing on the marginal fit of commercially pure titanium (Cp Ti) copings.A machined stainless steel die system with standard 0.5-mm copings was fabricated. Wax patterns were prepared by pouring the molten wax on a two-part stainless steel die.
