Carbonitrides

Carbonitrides

Titanium carbonitride Ti(C,N) powder is widely used for the production of metal-ceramic composites (cermets), which exhibit high hardness, excellent resistance to oxidation, high wear resistance and good toughness. Treibacher Industrie AG manufactures Ti(C,N) in various mixing ratios and grain sizes.

Titanium carbonitride Ti(C,N)
Carbonitrides are manufactured through the carbothermal reduction and nitridation of titanium oxide at high temperatures in a vacuum furnace. The material is then ground to achieve the required particle size distribution. The powder produced using this patented procedure has a spherical morphology and exceptionally narrow particle size distribution when compared with titanium carbonitride (TI(C,N)) produced from titanium metal.

  • Typical mixing ratios TiC/TiN 50/50, 30/70, 70/30
  • Grain sizes: 0.9 – 2.1

 
Special carbonitrides (e.g. Zr(C,N)) on request.

Applications

Cermets
Titanium carbonitrides are the raw material for producing cermets, a metal-ceramic composite similar to hard metal that exhibits high hardness, excellent resistance to oxidation, high wear resistance and good toughness.

Cermets are used as tools for machining metals. Just like classic WC-Co hard metals, cermets also require special additives such as Mo2C, TaC, NbC and, in special cases, WC. These additives can also be manufactured in the form of solid solution mixed crystals with titanium carbonitride.

In combination with Al2O3, Ti(C,N) offers an extremely wear-resistant cutting ceramic for machining e.g. cast iron.
