Titanium carbide

Titanium is a chemical element with the symbol Ti and atomic number is 22. It has a low density and is a strong, lustrous, corrosion-resistant (including sea water, aqua regia and chlorine ) transition metal with a silver color. Titanium carbide, TiC  is an extremely hard (Mohs  9-9.5) refractory ceramic material, similar to tungsten carbide.  


Increase the wear, corrosion and oxidation resistance of a tungsten carbide cobalt materials. It forms a solid solution that is more brittle and susceptible to breakage than the original material.

Chromium carbide

Chromium has the symbol Cr and atomic number 24. It is a gray hard metal with a high melting point. Chromium is well recognized due to its high corrosion resistance and hardness.

Chromium carbide (Cr3C2) is an extremely hard refractory ceramic material, usually processed by sintering. It has the appearance of a gray powder with orthorhombic crystal structure. 


Chromium is highly corrosion resistant, and does not oxidize at high temperature (1000-1100 °C). The thermal expansion coefficient of chromium carbide is almost equal to that of steel, reducing the mechanical stress buildup at the layer boundary.


Chromium carbide is used as a thermal spray material for protecting the underlying metal surface, and as an additive to corrosion-resistant and  wear-resistant materials. Widely used in coatings of bearings, seals, orifices, and valve seals. With a fine-crystal phase, chromium carbide inhibits growth of sub-micrometer grains during pressing and sintering, like vanadium carbide,
