The electrochemical properties of Ni 3 C carbide
The nickel carbide Ni 3 C is an endothermic compound with Δ H 0 = 55,670 J mol −1 and S 0 = 106.32 J mol −1 K −1 [ 14 ]. Since the metal-carbon bonding is weak in the nickel carbide, its oxidation is accompanied with the release of free carbon, similar to the oxidation of other endothermic carbides Fe 3 C, Co 3 C [ 31, 32 ].

We report a new atomic layer deposition (ALD) process for nickel carbide (Ni 3 C). The process uses bis(1,4-di-tert-butyl-1,3-diazabutadienyl)nickel(II) and H 2 plasma and is able to produce smooth, pure, crystalline Ni 3 C thin films in an ideal self-limiting ALD growth fashion.Using this ALD process, a uniform thin layer of Ni 3 C can be …

The formation and decomposition of nickel carbide in evaporated nickel
Auger electron spectroscopy and X-ray photoelectron spectroscopy were used to study nickel carbide (Ni 3 C) formed during the evaporation of nickel onto the surface of single-crystal graphite. It is shown that Ni 3 C formed in this manner extends from the surface to close to the interface. A model is proposed to explain the mechanism of Ni …

Nickel vacancy islands are observed at the periphery of rotated grains and indicate Ni(2)C dissolution after graphene growth. Density functional theory (DFT) calculations predict a very weak (van der Waals type) interaction of graphene with the underlying Ni(2)C, which should facilitate a phase separation of the carbide into metal …

Ownership: Bust the rust
With the nickel, you don't have to worry about that, because the nickel protects the surface." Although the silicon carbide in Continental's NiC3 is chemically identical to the grit in sandpaper, barrels feel smooth since the particles are only three microns in diameter and represent less than 5 percent of the mixture's weight.
