“…1a). Several scientists in their studies (Table 3) reported similar results [2,4,6,[15][16][17][18][19], which confirm that the SSE act as effective inhibitors. The evolution in inhibition efficiency may be attributed to the adsorption of the particles at the carbon steel (X52) surfaces [20].…”

Saccocalyx satureioides as corrosion inhibitor for carbon steel in acid solution

et al. 2016

View full text Add to dashboard Cite

The inhibitory effect of the crude ethyl acetate extract of Saccocalyx satureioides was estimated on the corrosion of carbon steel (X52) in 1 M HCl solution sing weight loss measurement, potentiodynamic polarization, electrochemical impedance spectroscopy and scanning electron microscopy techniques. Potentiodynamic polarization curves indicated that the plants extract behaves as a mixed-type inhibitor. The adsorption of the inhibitor on the carbon steel surface was found to follow Freundlich adsorption isotherm. The free energies, enthalpies and entropies for the adsorption and dissolution process were discussed in details. The inhibiting action increases with increasing concentration of the extract. The results obtained show that the extract of the aerial parts of Saccocalyx satureioides could serve as an effective corrosion inhibitor of carbon steel (X52) in hydrochloric acid medium.

“…Only one capacitive loop at the higher frequency range is observed which means that the corrosion of CS is controlled by the charge transfer process [16,17]. The increasing diameter of loop obtained in 1 M H 2 SO 4 in the presence of EAE and BE indicated the corrosion inhibition and the strengthening of inhibitor film [18].…”

Corrosion inhibition of carbon steel in 1 M H2SO4 solution by Thapsia villosa extracts

et al. 2016

Ethyl acetate extract (EAE) and butanolic extract (BE) of Thapsia villosa were investigated as corrosion inhibitors of Carbon Steel (CS) in 1 M H 2 SO 4 using electrochemical impedance spectroscopy (EIS) techniques, potentiodynamic polarization and weight loss measurements. The effect of temperature on the corrosion behavior of CS was studied in the range of 20-40°C. The experimental results show that EAE and BE are good corrosion inhibitors and the protection efficiency increased with increasing concentration of the extracts, but decrease with rise in temperature. The EAE and BE act as a mixed types inhibitors. The adsorption of extracts on CS surface follow Langmuir isotherm. The apparent energies, enthalpies and entropies of the dissolution process were discussed.

“…Nyquist plots are characterized by a semicircle or capacitive loop from high to low frequencies where these capacitive loops are ascribed to the double layer capacitance and charge transfer resistance (Okafor et al 2009). In this study, the obtained curves are approximated by a single capacitive semicircle which is ascribed to the double layer capacitance and charge transfer resistance (Okafor et al 2009;Raja et al 2013). Increasing impedance loop diameter has a relation to decreasing corrosion rate.…”

Sn-Ag based solder alloy seems to be a promising lead-free solder for the application on electronic assembly. The corrosion behavior of different lead free solder alloys such as Aloi pateri berasaskan Sn-Ag berpotensi menjadi pateri bebas-Pb untuk diaplikasikan sebagai pemasangan elektronik. Tindak balas kakisan aloi pateri bebas Pb yang berbeza seperti dikaji dalam larutan 3.5% NaCl menggunakan upaya dinamik pengutuban dan spektroskopi impedans elektrokimia. Mikroskop imbasan elektron (SEM), spektroskopi sinar-X tenaga terserak (EDX) dan pembelauan sinar-X (XRD) telah digunakan
