Influence of epitaxy and ordering on the mechanical behaviour of an oxide layer on a metallic substrate

EQCM studies on oxidation of metallic nickel electrode in basic solutions

“…This is the result of a mismatch between the structures of Ni(II) compounds (NiO or/and Ni(OH) 2 ) and metallic nickel. Reported in the literature values of the stress force acting parallel to the NiO(or Ni(OH) 2 )/Ni interface vary from tenths/ hundreds of MPa [71,72] to 1-3 GPa [73].…”

Elaboration and characterisation of plasma sprayed alumina coatings on nickel with nickel oxide interlayer

“…3 Now, this process has never been tested with nickel substrates, which might however present industrial interest in applications such as Waste-to-Energy plants [8,9]. A priori, nickel seemed to be a good candidate for this process insofar as its oxidation is considered producing the only oxide NiO, which grows by epitaxy on the metal [10], similarly as Fe1-xO on iron steels.…”
