Cyclic oxidation behaviour of electrodeposited Ni3Al–CeO2 base coatings at 1050 °C
چکیده انگلیسی

This paper presents the cyclic oxidation behaviour of electrodeposited pure, nano CeO2 (9–15 nm)- and micron CeO2 (5 μm)-modified Ni3Al coatings on Fe–Ni–Cr substrate at 1050 °C for periods up to 500 h. The pure Ni3Al coating had a marginal resistance to cyclic oxidation at 1050 °C, while the CeO2-dispersed Ni3Al coatings showed much better cyclic oxidation resistance. This difference was attributed to many beneficial effects of CeO2 including changing the growth mechanism of α-Al2O3 scale, reducing the growth rate of the scale, improving mechanical properties of the scale, and reducing void formation at the scale/coating interface and at the scale-grain boundaries.
