Abstract
The atomic and electronic structures of Me/ZrO 2(0 0 1) interfaces, where Me is Ni, Fe or a Ni–Fe alloy, are investigated by the plane wave pseudopotential method within density-functional theory. The work of separation of metal films from oxide substrate for the O- and Zr-terminated Me/ZrO 2(0 0 1) interfaces is calculated. High adhesion at both Me/(ZrO 2) O and Me/(ZrO 2) Zr interfaces is found. The effect of oxygen vacancies on the adhesion at the metal–ceramic interfaces is also investigated. It is shown that Ni(Fe)–O interaction at the O-terminated interface weakens in the presence of interfacial oxygen vacancies. At interfaces with Ni–Fe alloys the adhesion depends strongly on the composition of the interfacial layers and their magnetic properties.
