Description	Eutectic ceramic Al2O3-ZrO2-SiO2 also termed Eucor (as a top coat) and CoNiCrAlY (as bond coat) coatings were sprayed onto the surface of newly developed fine-grained cast polycrystalline nickel-based superalloy Inconel 713 LC by means of water stabilized plasma (WSP) and atmospheric plasma spraying (APS) respectively. After the spraying were all the samples annealed at the temperature of 950 C for 10 hours, and followed separately by isothermal heat treatment at 900 C for 10, 50, 100, 200 and 500 hours in ambient atmosphere. Eucor microstructural changes and as well the changes at top coat/bond coat interface were investigated by means of scanning electron microscope with an energy dispersive microanalyzer. The microstructure of APS CoNiCrAlY bond coat consisted of flattened splats, partially unmelted particles and oxides, which were formed across splats interfaces in interaction with ambient atmosphere during spraying. The top coat near-eutectic composition allowed to form Eucor amorphous structure Eutectic ceramic Al2O3-ZrO2-SiO2 also termed Eucor (as a top coat) and CoNiCrAlY (as bond coat) coatings were sprayed onto the surface of newly developed fine-grained cast polycrystalline nickel-based superalloy Inconel 713 LC by means of water stabilized plasma (WSP) and atmospheric plasma spraying (APS) respectively.
