Atomic layer deposited TiO2 protects porous ceramic foams from grain boundary corrosion
Source abstract
Abstract
Abstract Intergranular corrosion causes a significant loss of compressive strength in highly porous TiO2 foams. In this study, the resistance of conformal atomic layer deposited (ALD) coatings against intergranular corrosion has been investigated. ALD coated TiO2 foams maintained 107% ± 20% and 94% ± 10% of their initial compressive strength for films deposited at 150 °C and 250 °C, respectively. After an immersion period of 28 days in 1 mM HCl, amorphous films showed greater potential in corrosion protection of polycrystalline TiO2 foams. However, anatase coatings with sufficient protection may be more beneficial for cell-material interactions.
