Abstract
The current study investigates the thermally grown oxide layers (of the order of 5–10 μm thick) on Inconel 617 at elevated temperature of 950 °C in helium and air atmospheres using nanoindentation and nanoscratch techniques. Nanoindentation is also used to calculate the fracture toughness of the oxides using the crack initiation method. The oxide generated in helium tends to be more brittle with fracture toughness of 1.67 MPa.m1/2 whereas the oxide in air has a value of 2.18 MPa.m1/2. Hardness and elastic modulus extracted from nanoindentation are employed to calculate the adhesion and shear strength of the oxides using scratch technique. The oxide formed in helium exhibited higher adhesion strength compared to the oxide formed in air. The oxide in helium requires a higher load to break through the layer.
