“…In addition, the adsorbed S might hinder or delayed passivation, as it hindered the available sites for hydroxyl ion adsorption, a precursor for passive film formation [ 7 ]. Furthermore, the formation of S-containing phases led to localized acidification, which also contributed to the degradation of the Fe matrix [ 33 ]. As our electrochemical tests proved, Fe/ZnS showed a significantly enhanced corrosion current density, which was almost five times that of the Fe part.…”

Iron (Fe) has attracted great attention as bone repair material owing to its favorable biocompatibility and mechanical properties. However, it degrades too slowly since the corrosion product layer prohibits the contact between the Fe matrix and body fluid. In this work, zinc sulfide (ZnS) was introduced into Fe bone implant manufactured using laser additive manufacturing technique. The incorporated ZnS underwent a disproportionation reaction and formed S-containing species, which was able to change the film properties including the semiconductivity, doping concentration, and film dissolution. As a result, it promoted the collapse of the passive film and accelerated the degradation rate of Fe matrix. Immersion tests proved that the Fe matrix experienced severe pitting corrosion with heavy corrosion product. Besides, the in vitro cell testing showed that Fe/ZnS possessed acceptable cell viabilities. This work indicated that Fe/ZnS biocomposite acted as a promising candidate for bone repair material.

“…In the initial stage of the immersion test, obvious cracks appeared on the outer surface of SUS316 in the chloride solution. Subsequently, the number, width, and depth of the cracks increased rapidly, and the corrosion product layer took on a loose, porous honeycomb structure with low adhesion, making it easy to fall off [25,26]. Figure 8 shows the potentiodynamic polarization curves of amorphous coating fabricated with 26 L/h kerosene in HCl solutions with different concentrations.…”

Fe-based amorphous coatings are typically fabricated by high-velocity oxygen-fuel spraying using industrial raw materials. The bonding mode between the coating particles and the corrosion mechanism of the coating in the chloride-rich environment were studied. The results indicate that some fine crystallites such as α-Fe and Fe3C tend to precipitate from the amorphous matrix as the kerosene flow rate increases or the travel speed of spraying gun decreases. Moreover, some precipitates of the (Cr, Fe)2O3 nanocrystal were detected in the metallurgical interfaces of the amorphous coating. The relationship among the amorphous volume fraction, porosity, and spraying parameters, such as the kerosene flow rate and the travel speed of the spray gun, were established. Due to an oxidation effect during spraying process, atomic diffusion, crystallite precipitation and regional depletion of Cr occur in the area along the pre-deposited side near the metallurgical bonding interface, leading to the initiation of pitting. A model of pitting initiation and expansion of Fe-based amorphous coatings is proposed in this paper.

“…However, in some other industrial processes such as those involved in the petroleum and gas ones, most of these failures are caused by CO 2 and/or H 2 S [3][4][5][6]. Under these conditions, stainless steels are widely used to resist the corrosion caused by CO 2 and/or H 2 S [5][6][7][8] due to the formation of a highly protective layer formed in their surface [9][10][11][12][13][14][15]. One of the most popular cost-effective methods to ght corrosion and its implications in the destruction of metals is the use of corrosion inhibitors, especially organic ones, such as amines, amides, imidazolines and ammonium quaternary salts [16][17][18][19][20][21][22][23][24][25][26].…”

A cationic, Ammonium quaternary surfactant, obtained from avocado essential oil has been used as a corrosion inhibitor for LDX 2101 duplex stainless steel in a CO2-saturated 3.5% NaCl solution. Used techniques involved potentiodynamic polarization curves and electrochemical impedance spectroscopy. Results have shown that ammonium quaternary salt was an efficient mixed type of inhibitor although it affected more strongly the cathodic electrochemical reactions, with a decrease in the corrosion and current density and an increase in the pitting potential values; inhibitor had an efficiency that increased with its concentration from 0 to 25 ppm, but it decreased for higher concentrations. Inhibitor was adsorbed onto the steel surface on a mixed chemical-physical way dominated by a chemical type of adsorption, following a Langmuir type of adsorption isotherm. Corrosion process was charge transfer controlled and it was unaffected by the addition of the inhibitor. Theoretical studies in order to determine the relationship between electronic inhibitor properties and its inhibition efficiency have been carried out by using the DFT methodology.
