Abstract :
Aluminum oxide Al2O3 coatings on China Low Activation Martensitic (CLAM) steel substrates were prepared with atmospheric plasma spray (APS) method. Corrosion experiments of the coating specimens in static liquid LiPb were carried out in DRAGON-ST capsule for 5000 h at 550 °C. The results showed that there is no obvious thinning of external layer Al2O3 after 5000 h exposure. The γ phase Al2O3 in external layer and the dissolution of Ni in liquid LiPb from the edge of the internal layer Ni–Cr were the possible reasons for the corrosion of coatings.
