Hardening
Effective and efficient
In modern industry, materials have to withstand ever-increasing loads. Härteverfahren
sind deshalb unentbehrlich, um Bauteile widerstandsfähiger und langlebiger zu machen. Sie verbessern die Festigkeit und Verschleißbeständigkeit von Werkstoffen und sind unverzichtbar für moderne Fertigungsprozesse.
Particularly at process temperatures between 800 and 1,000 °C in vacuum or oxygen-free inert gas atmospheres (e.g., argon, nitrogen, helium), these processes enable precise material properties and high process control.

Typical applications
Hardening processes are used in numerous industries, including:
- Energy: Components for gas and wind turbines
- Chemical industry: Parts for corrosive environments and high-pressure processes
- Automotive: Transmission gears, shafts, and wear-intensive structural components
- Aerospace: Mechanical components for landing gears and flaps
Functions
The key material properties define their functions:
- Graphite: High thermal conductivity, chemical resistance, low thermal expansion, low electric resistivity
- Soft and rigid felts: Excellent insulation properties, available as flexible or dimensionally stable types
- CFC (Carbon Fiber Reinforced Carbon): Lightweight, high mechanical strength, thermal shock resistance, dimensional stability even under temperature fluctuations
Applications
Components made of graphite, soft and hard felts, as well as CFC (carbon fiber reinforced carbon) play crucial roles in hardening processes:
- Thermal insulation made from soft and hard feltsminimizes heat loss and ensures uniform process temperatures.
- Hard felt plates provide stability at high temperatures and protect against thermal stress.
- CFC charge carriers serve as lightweight, dimensionally stable supports that maintain their shape even under extreme conditions.
- Graphite gas flow elements optimize quenching in high-pressure gas quenching processes.
- Graphite or CFC heating elements ensure uniform heat input.
