“…The same order is found for the "log Z" values in Figure 3b. According to Zhang's research, the impedance modulus at the lowest frequency (Z f = 0.01 Hz) is another parameter in the Bode plot for evaluating the corrosion protection capability of the films; a greater impedance suggests a better corrosion resistance [35].…”

In this study, the corrosion resistance of titanium nitride (TiN), nitrogen titanium carbide (TiCN) and titanium-diamond-like carbon (Ti-DLC) films deposited on 316L stainless steel (SS) were compared via differences in the surface and section-cross morphologies, open circuit potential tests, electrochemical impedance spectroscopy and potentiometric tests. The corrosion resistance of the TiCN and Ti-DLC films significantly improved because of the titanium carbide (TiC) crystals that obstruct the corrosive species penetrating the as-deposited film in the electrolyte atmosphere. TiN exhibited the lowest corrosion resistance because of its low thickness and high volume of defects. The Ti-DLC film showed the lowest corrosion current density (approximately 4.577 μA/cm2) and thickness reduction (approximately 0.12 μm) in different electrolytes, particularly those with high Cl− and H+ concentrations, proving to be the most suitable corrosion protection material for 316L SS substrates.

“…The anti-corrosion ability of the as-fabricated The only difference in the EIS pattern of these samples is the size of the capacitor loop, which is caused by charge transfer during the testing process. In general, the better the corrosion resistance of the film, the larger the size of the corresponding capacitor circuit [37,38]. During the initial immersion (to 12 h), the low frequency capacitive arc radius first increased and then drop (to 36 h), which may be due to the superhydrophobic surface first inhibiting corrosion.…”

A superhydrophobic surface was constructed by a simple method of one-step electrochemical deposition in which methanol was used as carbon source and SiO 2 nanoparticles/nickel were used as dopant. Carbon-based films doped with SiO 2 nanoparticles and nickel (SiO 2 -Ni/a-C:H films) were fabricated for comparison experiments at various SiO 2 nanoparticle concentrations. It was turned out that the maximum contact angle of SiO 2 -Ni/a C:H film with SiO 2 nanoparticle concentration of 0.006 mg ml −1 (sample-3 film) is 162.4 degrees, and the minimum sliding angle is 1.2 degrees, showing excellent superhydrophobicity. Furthermore, dynamic potential polarization and electrochemical impedance spectroscopy (EIS) measurements indicated that the superhydrophobic film exhibited excellent anti-corrosion performance. It is very important for the industrial manufacture of corrosion-resistant superhydrophobic films and has broad prospects for expanding the application of carbon-based films.

Combination of Electrochemical Noise and Acoustic Emission for Analysis of the Pitting Corrosion Behavior of an Austenitic Stainless Cast Steel

2018

The pitting corrosion behavior of a high alloy cast steel is analyzed in a sodium chloride solution by combination of the electrochemical noise technique and the acoustic emission (AE) method. Four corrosion states are identified on the steel surface after the 70 h noise measurement test. The simultaneously monitored AE exhibits two types of acoustic signals. The first type of AE events is attributed to the local passive oxide breakdown and the pit initiation process and the second type of AE events is related to the subsequent associated hydrogen gas bubble evolution.
