ArCarb-LWR

Long-term Wear Resistant

ArCarb-LWR transforms its ultra-high temperature resistance capability into long-term wear and abrasion resistant components. An extremely low specific wear paired with tailored co-efficient of friction for braking and sliding elements enhances the tribology competence of a system. The added benefit of low density provides ease of control for fast moving or accelerated components.

Advantages

  • Low specific wear rate of 0.213 mm3/kJ ensures long life cycle of the component
  • The coefficient of friction (COF) can be tailored for friction or sliding structures
  • Lightweight structures due to low density of 1.9 g/cm3 (< Aluminium) leads to low energy consumption for fast moving and accelerated components

Application Domain

  • High wear resistant bearings
  • Sliders for high speed trains
  • Sealing rings
  • Brake discs/pads for automobiles motor bikes
  • Wind turbines
  • High performance elevators
