14 Jul 1997TL;DR: The tribological behavior of a titanium or titanium alloy article is improved by gaseous oxidation of the article at a temperature in the range of 500 to 725 °C for 0.5 to 100 hours, the temperature and time being selected such as to produce an adherent surface compound layer containing at least 50 % by weight of oxides of titanium having a rutile structure and a thickness of 0.2 to 2
Abstract: The tribological behaviour of a titanium or titanium alloy article is improved by gaseous oxidation of the article at a temperature in the range of 500 to 725 °C for 0.5 to 100 hours, the temperature and time being selected such as to produce an adherent surface compound layer containing at least 50 % by weight of oxides of titanium having a rutile structure and a thickness of 0.2 to 2 νm on a solid solution-strengthened diffusion zone wherein the diffusing element is oxygen and the diffusion zone has a depth of 5 to 50 νm.

TL;DR: In this paper, a diffusion barrier is defined as a layer of compositionally graded titanium nitride, having a nitrogen-rich portion and a nitrogenpoor portion, which is composed of at least about 40% (atomic) N and closer to the dielectric than the nitrogen-poor portion.
Abstract: A diffusion barrier film includes a layer of compositionally graded titanium nitride, having a nitrogen-rich portion and a nitrogen-poor portion. The nitrogen-rich portion has a composition of at least about 40% (atomic) N, and resides closer to the dielectric than the nitrogen-poor portion. The nitrogen-poor portion has a composition of less than about 30% (atomic) N (e.g., between about 5-30% N) and resides in contact with the metal, e.g., copper. The diffusion barrier film can also include a layer of titanium residing between the layer of dielectric and the layer of compositionally graded titanium nitride. The layer of titanium is often partially or completely converted to titanium oxide upon contact with a dielectric layer. The barrier film having a compositionally graded titanium nitride layer provides excellent diffusion barrier properties, exhibits good adhesion to copper, and reduces uncontrolled diffusion of titanium into interconnects.

TL;DR: A weld filler wire chemistry was developed for fusion welding 2195 aluminum-lithium as mentioned in this paper, which is an aluminum-copper based alloy containing high additions of titanium and zirconium.
Abstract: A weld filler wire chemistry has been developed for fusion welding 2195 aluminum-lithium. The weld filler wire chemistry is an aluminum-copper based alloy containing high additions of titanium and zirconium. The additions of titanium and zirconium reduce the crack susceptibility of aluminum alloy welds while producing good weld mechanical properties. The reduced weld crack susceptibility enhances the repair weldability, including when planishing is required.

TL;DR: A composite material having a carbon matrix, and a titanium-copper alloy dispersed in the carbon matrix and containing 1-80% by weight of titanium and 15.4-99% of copper is described in this article.
Abstract: A composite material having a carbon matrix, and a titanium-copper alloy dispersed in the carbon matrix and containing 1-80% by weight of titanium and 15.4-99% by weight of copper. The titanium-copper alloy is present in an amount of 2-85% based on a total weight of the carbon matrix and the titanium-copper alloy. The composite material may additionally contain carbon fibers dispersed in the carbon matrix. The composite material is produced by incorporating powder or melt of titanium and copper or copper alloy into a shaped body of carbon.
