Preparation and Thermal Shock Performance of ZrO<sub>2</sub>/NiCrAlY Thermal Barrier Coating

Electric spark deposition (ESD) combining with micro-arc oxidation (MAO) were employed to fabricate ZrO<sub>2</sub>/NiCrAlY thermal barrier coating (TBC) on GH4169 substrate. Firstly, a NiCrAlY coating with thickness of 250 μm was deposited on GH4169 substrate by ESD. Secondly, a Zr coat...
