Si/Mullite/Er(2)SiO(5) environment barrier coatings (EBCs) were prepared by chemical vapor deposition and plasma spraying on SiC/SiC composites. The oxidation behavior of the coatings at 1350 degree C was investigated, and the structure change of the coatings was analyzed by SEM, EDS and XRD. The re...
