Semiconducting properties of passive films formed on AISI 420 stainless steel in nitric acid solutions
This study focuses on the semiconductor properties of passive films formed on AISI 420 stainless steel immersed in four nitric acid solutions under open circuit potential (OCP) conditions. For this purpose, the passivation parameters and semiconductor properties of passive films were derived from potentiodynamic polarization and Mott–Schottky analysis, respectively. The OCP plots showed that th...
متن کاملA Review on the Semiconducting Behavior of Passive Films Formed on Mg Alloys by Mott–Schottky Analysis
Mg alloys have a vast usage where weight reduction is really significant since they do the features really well for materials of ultra-light weight. However, Mg is inherently a reactive metal and its alloys generally possess quite weak corrosion resistance that widely restricts their technological usages, especially in some rough service conditions. Despite, many investigations on the passive a...
متن کاملRecent advances on physico-chemical characterization of passive films by EIS and differential admittance techniques
Thin Nb2O5 anodic films ( 20 nm thick) grown in phosphoric acid solution have been characterised by EIS and differential admittance study in a large range of potential and frequency. The overall electrical behaviour has been interpreted by means of the theory of amorphous semiconductor Schottky barrier in presence of a non-constant density of states (DOS). A comparison of DOS for films grown in...
متن کاملPassivity of AISI 316L stainless steel as a function of nitric concentration
In this study, electrochemical behaviour of passive films formed on AISI 316L stainless steel (AISI 316L) in three acidic solutions concentrations (0.3, 0.6, and 0.9M HNO3) under open circuit potential conditions were evaluated by potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS) techniques. The potentiodynamic polarization results showed that...
متن کاملThe Effect of Chloride Ions Concentration on the Electrochemical Behavior of AISI 410 Stainless Steels in Simulated Concrete Pore Solution
The effect of chloride ions concentration on the electrochemical behavior of AISI 410 stainless steel in the simulated concrete pore (0.1 M NaOH + 0.1 M KOH) solution was investigated by various electrochemical methods such as Potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Potentiodynamic polarization curves revealed that increasing chlori...
