Corrosion resistance of nanostructured TiB2 films in 3% NACl solution

The paper examines the corrosion behavior of amorphous TiB 2 films 70–250 nm in thickness and amorphous–crystalline films with crystals 15–90 nm in size in 3% NaCI solution. It is shown that the corrosion resistance and passivation anodic potential increase with thickness of TiB 2 amorphous films. I...

Description
Summary:The paper examines the corrosion behavior of amorphous TiB 2 films 70–250 nm in thickness and amorphous–crystalline films with crystals 15–90 nm in size in 3% NaCI solution. It is shown that the corrosion resistance and passivation anodic potential increase with thickness of TiB 2 amorphous films. It is also established that TiB 2 films are oxidized through pitting corrosion. The corrosion instability of amorphous films is mainly due to their interaction with impurity (in particular, oxygen and carbon) structural inhomogeneities and of amorphous–crystalline films due to the interaction with amorphous–crystalline boundaries. The corrosion resistance of amorphous TiB 2 films is approximately 4000 times higher than that of bulk powder material and 8 to 10 times higher than that of amorphous–crystalline films.
