Tribological Properties of Ionic Liquids

An ionic liquid is a liquid salt consisting of anions and cations. Since Wilkes [1] synthesized a low melting point ionic liquid that is stable in air in 1992, there has been active fundamen‐ tal research and engineering development directed at applications. In the field of tribology, where application is focused toward lubricants, the number of related papers [3]-[28] has in‐ creased every yea...

Structural and Tribological Properties of Amorphous Carbon Nitride Thin Films Grown by Plasma Enhanced Chemical Vapor Deposition

This paper reports on the effects of nitrogen dilution on the structure, bonding and tribological properties of nitrogendoped amorphous carbon films (a-C:H:N) deposited by r.f. glow discharge from CH4-N2 mixtures on silicon substrates. For different N2 fractions, film structure and chemical composition were examined using Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). The mechan...

The electrodeposition of zinc alloys from ionic liquid electrolytes

Electrodeposited zinc alloys have long been recognised as effective barrier and sacrificial coatings for ferrous substrates. The effect of alloying zinc with, in the main, more noble metals, has produced finishes of higher corrosion resistance than simply electrodeposited zinc. In this manner zinc alloys such as zinc-nickel, zinc-cobalt and zinc-iron are routinely electrodeposited on an industr...

Electrodeposition at room temperature of amorphous silicon and germanium nanowires in ionic liquid

The electrodeposition at room temperature of silicon and germanium nanowires from the airand water-stable ionic liquid 1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (P1,4) containing SiCl4 as Si source or GeCl4 as Ge source is investigated by cyclic voltammetry. By using nanoporous polycarbonate membranes as templates, it is possible to reproducibly grow pure silicon and germ...
