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 ...

Post-fire Metallographic and Mechanical Performance of Industrial Pure Titanium
2019 9th International Conference on Fire Science and Fire Protection Engineering (ICFSFPE), 2019As industrial pure titanium is widely use in chemical equipment, research on the relevant safety properties after a fire accident is also necessary. Simulated fire experiments were carried out using diesel combustion, and a constant temperature heating experiment was performed.

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

The new reusable laparoscopic multi-fire clip-applier for titanium clips
Minimally Invasive Therapy & Allied Technologies, 1996SummaryThis article presents a new clip-applier characterized by its reusable construction with interchangeable disposable clip storage magazines containing eight titanium clips. The advantage of this multi-fire clip-applier is evident in laparoscopy under the conditions of pneumoperitoneum because the clips are loaded intra-abdominally.

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.

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 ...

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.

Bond strength of three porcelains to two forms of titanium using two firing atmospheres
The Journal of Prosthetic Dentistry, 2000Problems with casting and porcelain bonding are encountered when titanium is used in metal-porcelain restorations. The oxidation characteristics of titanium are the main problem. The bonding mechanisms in titanium-porcelain systems are complex and poorly understood.An in vitro investigation was performed to evaluate the bonding characteristics of 3 ...
