Electrical Resistance of Resistance-Sintered Titanium and Its Alloys

Biomedical Applications of Titanium and its Alloys

Materials used for biomedical applications cover a wide spectrum and must exhibit specific properties. The most important property of materials used for fabricating implants is biocompatibility, followed by corrosion resistance. The main metallic biomaterials are stainless steels, cobalt alloy, and titanium and titanium alloys. Stainless steel was the first metallic biomaterial used successfull...

Mechanical behaviour of pressed and sintered titanium alloys obtained from prealloyed and blended elemental powders.

The applicability of irregular prealloyed Ti-6Al-4V powder for the fabrication of titanium products by pressing and sintering and its employment as a master alloy to obtain the Ti-3Al-2.5V alloy was studied. To this end, the starting powders were characterised by dilatometry, differential thermal analysis and XRD. Green samples were obtained by cold uniaxial pressing, and the evolution of the m...

Electrical Resistance of Laser Sintered Direct-Write Deposited Materials for Microelectronic Applications

The direct write technology provides an interesting opportunity for plugging blind via holes as a more precise alternative to currently used screen printing processes. This technology provides a complete, void-less filling of the via and fabrication of the interconnects extending from the via in one single step. After deposition, the material is heat treated (sintered) to densify into a highly ...

Corrosion Resistance of Dental Alloys

Metals and metallic alloys are unavoidable materials in everyday dental use for the making of fillings, cast cores and post systems, individual crowns, implantants’ suprastructures, dentures and orthodontic devices. They still belong to the vital materials in dentistry. Applied alloys in a mouth are exposed to the influence of chemical, biological, mechanical, thermal and electrical forces whic...
