Abstract Simulation experiments using oxide thin films with analogues composition and thickness of passive films on Fe–Cr alloys have been performed to reveal the function of alloying elements in passive films. The objective of the present paper is to review recent results of the simulation experiments using Fe2O3–Cr2O3 films.

An estimate of the ductility of a passive film can be made by straining the metal covered by the film and observing the current required to keep the film at its normal thickness. For the metals tested, the relative ductilities of passive films as measured by this technique decrease in the order tantalum; 16 Cr, 14 Ni, bal. Fe; type 304 stainless steel;

Passive films at the nanoscale
Electrochimica Acta, 2012Abstract The nanometer scale chemical and structural aspects of ultrathin oxide passive films providing self-protection against corrosion to metals and alloys in aqueous environments are reviewed. Data on the nucleation and growth of 2D anodic oxide films, details on the atomic structure and nanostructure of 3D passive films, the preferential role of

Current developments of nanoscale insight into corrosion protection by passive oxide films [PDF]
Current Opinion in Solid State and Materials Science, 2018 Oxide passive films are a key for the durability of metals and alloys components as well as a central issue in corrosion science and engineering. Herein, we discuss current developments of the nanometer and sub-nanometer scale knowledge of the barrier ...

Growth dynamics and morphology of passive films
Physical Review E, 1996We study the passive layer formation observed when a metal is immersed in an oxidizing solvent and propose a model based on two different schemes to describe the evolution of the solid film and the liquid phase. The formation of the passive layer is simulated at a mesoscopic scale, whereas the concentrations in soluble species in the liquid are deduced

Thin film passive elements on polyimide film
Proceedings. 1998 International Conference on Multichip Modules and High Density Packaging (Cat. No.98EX154), 2002The General Electric Research and Development Center, Schenectady, NY, has teamed with Rensselaer Polytechnic Institute (RPI), Arizona State University (ASU) and Sheldahl, on the development of thin film deposition processes for the fabrication of passive elements on polyimide films. This program is targeted at processes for the fabrication of integral

ABSTRACTAlthough wafer curvature measurement provides a rapid and accurate determination of stress in a uniform thin film, the technique is not applicable to patterned films. To study the stress in metal lines, and the effect of passivation on that stress, it is necessary to use X-ray diffraction.

Evolution of passivity in air exposure of an iron passive film
Electrochimica Acta, 2006Abstract The evolution of passivity in air exposure of air-formed films on as-polished bare irons and electrochemically reduced bare irons was investigated by electrochemical methods. Passivity and surface structure were characterized by the recovery duration against open-circuit breakdown and the spontaneous potential, respectively.

Surface Modification of Nitinol by Biocompatible Passive Films
ECS Transactions, 2010Nitinol, near-equiatomic nickel-titanium alloy, exhibits unique properties, shape memory effect and superelasticity, and is therefore of a huge importance in biochemical engineering for medical devices. The high corrosion resistivity and biocompatibility are required in application of Nitinol as implant material for cardiovascular stents and ...
