Two types of coating-modified 3D C/SiC, coated with CVD SiC/SiC/SiC (type I) and CVD SiC/amorphous-BC/SiC (type II), are subjected to a 14vol.% H 2 O/8vol.% O 2 /78vol.% Ar atmosphere at 700, 1000 and 1200°C up to 100h. Microstructure and corrosion behaviour are investigated using a variety of characterization techniques. The type II shows a better oxidation resistance than type I...
An amorphous boron carbide (a-BC) coating was prepared by LPCVD process from BCl 3 –CH 4 –H 2 –Ar system. XPS result showed that the boron concentration was 15.0at.%, and carbon was 82.0at.%. One third of boron was distributed to a bonding with carbon and 37.0at.% was dissolved in graphite lattice. A multiple-layered structure of CVD SiC/a-BC/SiC was coated on 3D C/SiC composites...
