Plasma surface treatment for ceramic and CMC surface modification

Plasma surface treatment for ceramic and CMC surface modification

Surface modification of C/C and C/SiC using an atmospheric pressure plasma jet system (APPJ)

  • Only surface is affected by the treatment.

  • Cleaner and more eco-friendly compared to wet etching.

  • Compressed air as plasma gas.

  • No need of vacuum (required for low-pressure plasmas).

  • Inexpensive.

  • It can operate continuosly.

  • Easy to automate

New method to increase joining performances :

C/SiC surfaces: non –modified and modified surfaces by palsma treatment; selective removal of fibers
