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 ...

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

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.

Effect of Titanium Oxide on Fire Performance of Intumescent Fire Retardant Coating
Advanced Materials Research, 2014The objective of this research work was to study the thermal efficiency of intumescent fire retardant coating (IFRC) designed to protect structural steel in event of fire. IFRC has been effectively developed by using ammonium polyphosphate (APP), expandable graphite (EG), melamine (MEL), boric acid (BA), titanium oxide (TiO2), and bisphenol A BE-188 ...

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.

Dental Materials, 2003
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.
