Understanding Pyrolytic Carbon Coating
How pyrolytic carbon coating is created
Pyrolytic carbon coating is produced through a process called pyrolysis, which involves the thermal decomposition of hydrocarbons. This process typically occurs in a chemische aufdampfung (CVD) chamber under controlled conditions. The steps include:
- Purging the chamber with nitrogen and hydrogen gases.
- Heating the chamber to 700 °C in a hydrogen atmosphere for one hour.
- Replacing the hydrogen with a hydrogen-methane gas mixture.
- Gradually increasing the temperature to 1100 °C over 40 minutes.
- Allowing methane to decompose spontaneously at 1100 °C, forming hydrocarbon molecules that deposit onto the substrate.
This method ensures the formation of a durable and uniform coating. During carbonization, coke and volatile products are produced, which degrade into pyrolytic carbon, water, and gas. The result is a material with exceptional properties suitable for various applications.
