Thick, protective ALD coating on knife: silver knife coated with 100 nm Al2O3 ALD after 1 year indoor aging at the same ambient conditions as the knife shown in Fig. 5a. No tarnish spots were visible on the 100 nm coated knife, indicating a thicker ALD coating effectively coats any defects that may be present in early growth stages of ALD films.
