Characteristics and application range of chromium carbide

Overview of Chromium Carbide Cr3C2 Powder

Chromium (II) carbide is a ceramic compound that exists in several chemical compositions: Cr3C2, Cr7C3 and Cr23C6. Under standard conditions it exists as a grey solid. It is very hard and corrosion resistant. It is also a refractory compound, which means it retains its strength even at high temperatures. These properties make it useful as an additive to metal alloys. When chromium carbide crystals bond to a metal surface, it increases the metal's wear and corrosion resistance and maintains these properties at high temperatures. For this purpose, the hardest and most commonly used component is Cr3C2 . The mineral form of the Cr3C2 compound is cuprite.

Chromium carbide Cr3C2 powder application

Chromium carbide can be used for surface treatment of metal parts. Chromium carbide is used to coat the surface of another metal in a technique called thermal spraying. Cr 3 C 2 powder is mixed with solid nickel chromium. This mixture is then heated to a very high temperature and sprayed onto the object being coated, creating a protective layer. This layer is essentially its own metal matrix composite, consisting of hard ceramic Cr3C2 particles embedded in a nickel-chromium matrix. The substrate itself contributes to the corrosion resistance of the coating, as the metallic forms of nickel and chromium are corrosion resistant. After overspraying the coating, the coated part must be subjected to a diffusion heat treatment to achieve the best results in terms of bond strength and hardness to the base metal.

Another technique uses chromium carbide in the form of overlay plates. These are prefabricated chromium carbide coated steel sheets designed to be welded to existing structures or machinery for enhanced performance.

Chromium carbide is used as an additive in cutting tools made of cemented carbide to increase hardness by preventing the growth of large grains. The main component of most extremely hard cutting tools is tungsten carbide. Tungsten carbide is combined with other carbides such as titanium carbide, niobium carbide and chromium carbide and sintered with a cobalt matrix. Cr3C2 prevents the formation of large grains in the composite, resulting in a fine-grained structure with excellent hardness.

The unwanted formation of chromium carbides in stainless steel and other alloys can lead to intergranular corrosion.
