Working with Tantalum and Tantalum Alloys
CORROSION 2003, 2003Abstract Tantalum materials have been used in electronic, chemical processing, and other industries for many years. Solid tantalum shapes are readily produced using conventional ingot metallurgy followed by thermomechanical processing. Alloying tantalum with tungsten improves mechanical strength as well as corrosion resistance without ...

Electrodeposition of tantalum and tantalum-chromium alloys
Journal of Applied Electrochemistry, 1981As part of a programme to develop erosion resistant coatings for advanced gun barrels, electrodeposition of tantalum and tantalum-chromium alloys from fused Flinak has been investigated. Tantalum-chromium alloys containing 2–6% chromium were obtained by co-depositing tantalum and chromium from an electrolyte containing 10 wt% TaF5 and 0.5–1.5% Cr (as ...

Preparation of tantalum carbide films by reaction of electrolytic carbon coating with the tantalum substrate [PDF]
Journal of Alloys and Compounds, 2006 This article demonstrates that coatings of tantalum carbide can be obtained by electrodeposition of carbon in molten fluorides on a tantalum substrate as an alternative to the CVD process.

Journal of Applied Physics, 1966
Results are presented which indicate that the effects of sputtering voltage and current on the resistivity of films sputtered from pure tantalum appear to be traceable to the pressures and growth rates associated with each sputtering condition. From these data it can be deduced that the observed resistance variations are largely accountable in terms of

New applications for tantalum and tantalum alloys
JOM, 2000High-strength tantalum alloy usage has been limited since the cancellation of the manned space-power program in 1969. Yet, because of its unique combination of mechanical properties, fabricability, and high melting temperature, certain tantalum alloys are still used in applications where no other material is suitable, primarily for applications in the ...

Corrosion of Tantalum and Tantalum Alloys
2005Abstract Tantalum is one of the most versatile corrosion-resistant metals known. The outstanding corrosion resistance and inertness of tantalum are attributed to a very thin, impervious, protective oxide film that forms on exposure of the metal to slightly anodic or oxidizing conditions.

Slip Geometry of Tantalum and Tantalum Alloys
Physica Status Solidi (a), 1975The deformation behaviour of tantalum-rhenium, tantalum-niobium, electronbeam melted tantalum, and ultra high vacuum annealed tantalum is studied at temperatures 77 to 293 K. The slip geometry, morphology, and yield stress is determined as function of orientation, temperature, and mode of deformation. Alloying is observed to promote slip on the m.r.s.s.

Spectrographic Analysis of Tantalum and Tantalum Oxide
Applied Spectroscopy, 1963Tantalum metal is analyzed for 12 impurity elements by using a carrier distillation technique with a dc arc. The metal is oxidized in a muffle oven at 900°C. The oxide is mixed with a special carrier made of silver metal, silver chloride, and barium fluoride.
