chromium carbide

[′krō·mē·əm ′kär‚bīd]
(inorganic chemistry)
Cr3C2 Orthorhombic crystals with a melting point of 1890°C; resistant to oxidation, acids, and alkalies; used for hot-extrusion dies, in spray-coating materials, and as a component for pumps and valves.

Postalloy PS-150 is a tubular metal-cored hardfacing wire that provides a dense, heterogeneous deposit of vanadium-tungsten carbides, resulting in a great combination of abrasion and impact resistance that, according to the company, is superior to chromium carbide hardfacing alloys.
Both Postalloy 2826 and Postalloy 2828-FCO, hardfacing wire for use in extreme abrasion applications like bucket teeth, present wear characteristics similar to those of chromium carbide hardfacing products, the company reported.
014" chromium carbide alloy would then be applied at around 100p per pass, to provide wear resistance to the engine component, using the plasma system.
WEAR RESISTANCE LTD specialise in weld application of Tungsten or Chromium Carbide deposits, or a combination of both, to components which are subjected to excessive wear.
Some coatings that have been commercially produced consist of a monolayer of titanium carbide (TIC), titanium nitride (TIN), titanium aluminum nitride (TiA1N), titanium carbonitride (TiCN), chromium nitride (CrN), chromium carbide (CrC), or diamond-like carbon.
They should be protected by materials such as titanium, cast iron or stainless steel with a chromium carbide finish.
It is the formation of chromium carbide that compromises corrosion resistance when carbon is added to harden stainless steel by common methods.
White lamellas of nickel, light orbicular particles, lamellas of titanium silicides of complex composition, fine-dispersed particles of chromium carbide of up to 5 mm size, and dark coarse particles and lamellas of aluminium oxide prevail in it.
Abresist basalt, Alresist alumina ceramic, Kalcor zirconium, and Kalrnetall chromium carbide.
The actual coating particles can be either tungsten carbide (WC), chromium carbide (Cr3C2), or a combination thereof.
A chromium carbide and nickel base metallic coating is formulated for abrasion resistance.
