Chromium(II) carbide - Wikipedia
Chromium(II) carbide is a ceramic compound that exists in several stone compositions: Cr 3 C 2, Cr 7 C 3, and Cr 23 C 6.At standard conditions it exists as a gray solid. It is extremely hard and corrosion resistant. It is also a refractory compound, which means that it retains its strength at high temperatures as well. These properties make it useful as an additive to metal alloys.

Chromium Carbide - an overview | ScienceDirect …
Unlike TiC, chromium carbide has been much less studied. 40–51 Very little information regarding the various phases and properties of chromium carbides has been characterized and reported in the literature. Similar to β-titanium, chromium metal has the bcc (body centered cubic) structure. As a result, the same arguments for interstitial carbon apply, i.e. a change to a close-packed structure.

Thickness Limitation. A&A Coatings Plasma Sprayed Chromium Carbide was designed for use in thin coatings, not more than .020″ thick. If sprayed thicker, the probability of cracking and delamination will increase rapidly, as is the case of thick coatings of all fine powders.
Tungsten/Chromium Carbide Coatings - Extreme …
Tungsten carbide with a Vickers number of 1700-2400 (85 HRC equivalent) is composed of 90% carbide particles by weight, 80% by volume. Most standard wear resistant alloys contain a maximum of 35% by volume of softer chromium carbide. We offer coating formulation options, mainly tungsten carbide (C1000, C1000Ni, C9000) and chromium carbide (C4000).
Chromium carbide coatings HVOF HVAF spray …
Thermal sprayed chromium carbide coatings combat high-temperature wear due to the high wear resistance imparted by the hard carbide particles and the high temperature oxidation resistant nature of the Cr 2 O 3 oxide formed over both phases of CR3C2-NiCr.. While tungsten carbide coatings provide better wear resistance when temperatures are under 510°C (950°F), high velocity sprayed chrome ...
