An environmental barrier coating, a method of application thereof, and an article made thereby suitable for protecting components exposed to high-temperature environments with improved delamination resistance and cavitation resistance. The environmental barrier coating system for a silicon-containing substrate includes a bond coat layer on the silicon-containing substrate and at least one ceramic environmental barrier layer on the bond coat layer. The bond coat layer includes silicon and at least one doping material including elemental titanium. The doping material is located at grain boundaries within the bond coat layer in sufficient quantity to improve the delamination resistance and the cavitation resistance of increase the bond coat layer.
