By using the equation C = Atn, where C is corrosion rate after t years, A is corrosion rate after the first year of exposition, and n is constant, based on n values, the corrosion rate values of aluminium samples are predicted.
The goal was to develop an evaluation equation that could be used to estimate the breakdown stress of a pipeline that has suffered from corrosion due to a single corrosion fault. After the ANN was trained, its performance was measured against predetermined benchmarks using a validation and ...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
In this study, we report an eco-friendly and facile process for the synthesis of biochar, BC, and a cobalt-biochar nanocomposite, Co-BC, using rice straw biomass. We constructed two superhydrophobic coatings on steel substrates using potentiostatic elect
The standard absorption curve of 2-MBT was obtained using six different concentrations (0.011, 0.0144, 0.0279, 0.0517, 0.0751, and 0.1014 g/L) and the corresponding fitting equation is A = 107.67507c−0.01539 (A represents absorbance and c is the corresponding concentration (g/L)) with ...

sweep rate of 1 mV/s. Table1lists the electrochemical polarization characteristics, including corrosion potentials (Ecorr), corrosion current densities (icorr), anodic Tafel slopes (βa) and cathodic Tafel slopes (βc). The inhibition efficiencies (η%) are obtained using the equation below42,43...
It has been shown that the microscopic scale and morphology determine the solid/liquid contact and control the adhesive strength of water droplets on the superhydrophobic surface36,37. As described by the water contact angle equation proposed by Cassise and Baxter38, cos θ ′ = f ...
In this equation, anodic and cathodic Tafel constants are represented by ba and bc, respectively. Polarization response of about ±10 mV around corrosion potential can be sued to measure the slope ΔE/ΔI and corrosion current can be calculated using the above equation provided Tafel constants ar...
