The chemistry and microstructure of ceramic coatings of Zr02 with 8 and 20 wt% Y2O3 plasma deposited on the NiCrFe substrate with the NiCr25Al6Fe2Y0.4 interlayer were investigated using scanning, analytical microscopy and X-ray phase analysis. An amorphous phase and fine crystalline zone adjacent to the ceramic and metallic layer was detected using transmission electron microscopy. On the other hand, another zone, which was nanocrystalline with some contribution of amorphous phase was observed in the NiCrAIFeY interlayer close to the NiCrFe substrate.
