Abstract

In order to further improve the oxidation protective ability of (ZrB₂-SiC)/SiC coated graphite, ferrocene was introduced into the outer ZrB₂-SiC coatings during pack cementation process. The ferrocene addition increased the porosity of the outer ZrB₂-SiC coatings, which was favorable to thermal shock resistance of (ZrB₂-SiC)/SiC coated specimens. The ZrB₂-SiC coating with 3 wt% ferrocene (ZS50-3f) has optimum oxidation protective ability. Its weight retention after 15 thermal shock cycles between 1500 °C and room temperature was 96. 2%. The weight loss of ZS50-3f was only 0.2% after 19 h oxidation at 1500 °C.
