Corrosion Behaviour of Stainless Steel (AISI 321) in Alcoholic-H<SUB>2</SUB>SO<SUB>4</SUB> Mixtures

Micro abrasion-corrosion of AISI 316L stainless steel

In this study, the synergistic effects of abrasion and corrosion on AISI 316L stainless steel have been investigated using a micro-abrasion test rig. A series of results from abrasioncorrosion tests conducted using the micro-abrasion rig are presented. AISI 316L stainless steel has been studied under both pure abrasion and abrasion-corrosion conditions simulated by either distilled water or 3.5...

Determination of susceptibility to intergranular corrosion and electrochemical reactivation behaviour of AISI 316L type stainless steel

In this study, double loop electrochemical potentiokinetic reactivation (DLEPR) test was applied to determine the degree of sensitization in 316L type stainless steel, where obtained results were correlated with revealed microstructures after oxalic acid test and weight loss measurements of Streicher and Huey acid tests. Best agreement was provided with test parameters which are 1 M H2SO4 and 0...

Corrosion Behaviour of Nickel Coated AISI 316 Stainless Steel as a Function of Annealing Temperature

AISI 316 stainless steels were coated with 250 nm Ni film by electron beam deposition and post-annealed at different temperatures with a nitrogen flow of 600 cm3min-1 nitrogen. The prepared samples were corrosion tested in 1.0 M sulphuric acid solution using potentiodynamic technique. Crystallographic and morphological structure of the samples were analyzedanalysed by X-ray diffraction (XRD) an...

The Effect of Solution Concentration on the Electrochemical Behaviour of AISI 321 Stainless Steel in Sulfuric Solutions

EFFECT OF IMMERSION TIME ON THE ELECTROCHEMICAL BEHAVIOUR OF AISI 321 STAINLESS STEEL IN 0.1 M H2SO4 SOLUTION

In this study, effect of immersion time on the electrochemical behaviour of AISI 321 stainless steel (AISI 321) in 0.1 M H 2SO 4 solution under open circuit potential (OCP) conditions was evaluated by potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Mott–Schottky analysis revealed that the passive films behave as n-type and p-type s...
