Ferro-TiC ?
- 'Ferro-TiC' is TiC based metal matrix composite. The rounded titanium carbide
(TiC) particles are uniformly exposed on the surface of materials and it provide
a combination of low coefficient of friction and a hardness higher than tungsten
carbide (WC).
- This unique combination makes the alloy bonded TiC materials especially
suited for wear resistant applications.
- Although TiC is harder, even than tungsten-carbide, Ferro-TiC could be
machined by a lathe, milling & grinding machine etc. in the HIP and annealed
state and then hardened by heat treatment to hardness 68-72 Rc.
Features
1. Excellent Wear Resistance and Lubrication
High wear resistance is probably Fe - TiC's best known characteristic. Exposing
titanium carbide micrograins after lapping and polishing at the working surface
leaves pick-up and galling problems in relief and minimizes metal-to -metal
contact. Their smooth, rounded structure offers an extremely slippery and non-abrasive
surface for contact.
2. Fe-TiC is the only machinable carbide composite
In annealed state, HRC43-45 hardness of Fe-TiC could be machined by a conventional
equipment. After quenching, it becomes one of HRC68-70 hardness carbide composites
which is stable in dimensional transformation within +/-0.00025mm/mm
3. Low density
Low density is 50% lighter than tungsten-carbide and also 15% lighter than
steel.
