摘要

The improvement of oxidation resistance of C/C composites by pack cementation and plasma spray technologies with SiC/gradient composition yttrium silicate multilayer coatings, was analyzed. The cryatalline structure of the synthesized yttrium silicate powder was measured with the Rigaku D/max3C X-ray diffractometer. The morphology of the as-prepared multilayer coatings was analyzed using jSM-5800 scanning electron microscope (SEM). The SiC/gradient yttrium silicate multilayer coating produced by pack cementation and subsequantly by plasma spray processes excellent thermal shock resistance and can protect the C/C composites from oxidation perfectly at 1773 K for an extended period of time.
