To understand the oxidation behaviors of NiCrAlY bond coats in thermal barrier coatings (TBCs) under external loads, uniaxial tensile and compressive experiments TBCs air at 900 °C for 100 h were investigated. Then, experimental results explained by first-principles simulation. The showed that rate coat was accelerated stresses. A 0.9 μm thickness, a thermally grown oxide (TGO) layer found with...

In the present study NiCrAlY bond coating layer was produced by electroplating against common atmospheric plasma spraying (APS). Both types of the bond coats were applied on IN738LC base metal then, the YSZ (ZrO2-8% Y2O3) thermal barrier top layer was coated by atmospheric plasma spray technique. Hot corrosion is one of the main destructive factors in thermal barrier coatings (TBCs) which come ...
