Photoelectrochemical analysis on the passive film formed on Fe–20Cr in pH 8.5 buffer solution
Electrochimica Acta, 2002 The electronic properties of passive film formed on Fe-20Cr stainless steel in pH 8,5 buffer solution were examined by the photocurrent measurements of the film. The passive film on Fe-20Cr exhibited an n-type semiconductor, which was confirmed by anodic

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

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

Photoelectrochemical study on the passive film on Fe
Corrosion Science, 2001 Electronic properties of the passive film formed on Fe in pH 8.5 buffer solution were examined by the photoelectrochemical spectroscopy. Photocurrent responses for the passive film on Fe with film formation potential are explained by the modified band ...

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

MRS Proceedings, 1990
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 ...
