Combined surface coatings with BoraSiC and vacuum plasma sprayed cordierite

The Oxidation Protection of CVD based coating systems on Carbon/Carbon and CMC (C/C-SiC) was improved by applying a plasma sprayed cordierite sealing layer (done by DLR). This combination has shown the best thermal shock resistance of all multilayers developed and/or tested within the HITHEX and the previous projects. Long-term oxidation tests are running to prove, if the system possesses a high potential for oxidation protection.

Short-term oxidation resistance under extreme thermal shock conditions can be guaranteed with the new developed combined coating system.
