Microstructural studies on EB-PVD deposited NiCrAlY, YSZ and lanthanum zirconate for thermal barrier applications

► TBCs of YSZ, La2Zr2O7, NiCrAl were deposited at low temperature by EBPVD. ► Substrate temperature of 400 °C was used, much lower than many reported literature. ► Desired phase, feather like microstructure for TBC is observed with sharp interface. ► Interface of bond coat-steel, bond coat‐La2Zr2O7, YSZ is discussed.
