TLDR
In this paper, a passive film formed anodically on nickel in borate buffer solution in both the passive and transpassive regions is found to be p-type in electronic character, corresponding to a preponderance of metal vacancies (over oxygen vacancies and nickel interstitials) in the barrier layer.About:

The history of the Point Defect Model for the passive state: A brief review of film growth aspects
TL;DR: A review of the history of the Point Defect Model (PDM) for the growth and breakdown of passive films that form on the surfaces of reactive metals in contact with corrosive, condensed phase environments is presented in this paper.

The passive behaviour of AISI 316 in alkaline media and the effect of pH: A combined electrochemical and analytical study
L. Freire,L. Freire,M.J. Carmezim,M.J. Carmezim,Mário G.S. Ferreira,Mário G.S. Ferreira,Maria de Fátima Montemor +6 more
TL;DR: In this paper, thin surface films were formed on AISI 316 immersed in alkaline solutions of pH ranging from 13 to 9 under open circuit potential conditions, and the electrochemical behaviour of the films formed under these conditions was evaluated by different electrochemical techniques: d.c. potentiodynamic polarisation, capacitance measurements (Mott-Schottky approach) and electrochemical impedance spectroscopy.

Graphene oxide/nickel oxide modified glassy carbon electrode for supercapacitor and nonenzymatic glucose sensor
TL;DR: Based on the extraordinarily properties of graphene oxide (GO), nickel oxide nanoparticles (NiONPs)/GO/glassy carbon (GC) modified electrode was prepared by electrodeposition of NiONPs on the GC surface previously modified with GO, which was characterized by scanning electron microscope (SEM), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV).

Passivity : the key to our metals-based civilization
TL;DR: In this paper, a review of passivity and passivity breakdown is presented, with emphasis on the physical models that have been proposed to account for most, if not all, experimental observations, and to provide a robust basis for predicting the occurrence of passingivity breakdown in any given system.

Theory of Steady‐State Passive Films
TL;DR: In this paper, the steady-state properties of passive films were investigated in aqueous environment and a point defect model was developed to predict the steady state thickness of the barrier film and the log of the steadystate current will vary linearly with applied voltage.
