Abstract
Catalycity (kw) of CVD-SiC coated C/C is measured by plasma test using a Russian Plasmatron. The catalycity increased with increasing temperature and with decreasing pressure. The catalycity in Air (kwAir) was ranged between 1.0 and 4.5 m s−1. This shows the applicability of the CVD-SiC coating to the re-entry space vehicles of HOPE-X . The surface of the specimen was covered with SiO2 after the tests. The low kw was caused of the property of SiO2.
