Tantalum electrodeposition using a nanoporous anodic alumina template and a nanostructured gold/nickel-chromium glass-ceramic substrate [PDF]

open access: yesarXiv
Electrodeposition of tantalum coating was performed from an ionic liquid, BMP[Tf2N], in the presence of dissolved anhydrous TaF5 and LiF. Superficial X-ray photoelectron spectroscopy supplemented by an argon ion etching and depth profiling has proven the presence of the tantalum metal inside a thin coating deposited via a porous anodic alumina template.
