Corrosion behaviors and mechanisms of ytterbium silicate environmental barrier coatings by molten calcium-magnesium-alumino-silicate melts

[Display omitted] •Phase composition significantly influenced the corrosion behaviors and mechanisms.•The Yb2O3-rich coatings exhibited better corrosion resistance.•The existence of appropriate amount of Yb2O3 can improve the corrosion resistance.•The formation reaction of garnet was beneficial to f...
