The theory basis is that: when silicide is added into present EBC, if cracks appear in coating used in a combustion gas environment, silicide on the crack surface or near the crack will be rapidly oxidized to generate silicon dioxide (SiO2) or another oxide, thus the SiO2 can be used as a mobile phase to seal the cracks; furthermore, the volume expansion caused by the oxidation reactions and the high expansion coefficient of the silicide generate pressure stress on the cracks to accelerate the healing of the cracks; so the prepared environmental barrier coating has a good self-healing ability.
