The oxidation behaviour of carbon/carbon composites, with the addition
of various inhibitors, has been studied using thermodynamic analysis
and microscopy. The effects of ZrB2, B, SiE(4), tetraethylorthosilicat
e (TEOS), tributylphosphate (TBP) and additions of treatment with H3PO
4 were compared using L(8) orthogonal array table and analysed by the
ANOVA-TM program.
