“…The Pourbaix diagram for Zn shows that in acidic environment, no surface oxides of Zn are stable, while under neutral or slightly alkaline conditions (as those in human body) zinc has the tendency to be passivated. It is generally accepted that in neutral and in alkaline solutions the dissolution-passivation of Zn involves a number of intermediate species according to the following reactions (Abd El Aal, 2006;Thomas et al, 2012):…”

“…Studies have previously related the dropped in passivity to SO 4 2– ’s ability to be adsorbed on the passive film, induce an electrostatic field at the film surface, and eventually penetrate and disrupt the oxide film. , Sulfates often encourage localized attack, which explains the observed localization of the corrosion product in S4 compared to S3. Though EDS did not detect sulfur (S) in the corrosion layer, it is possible that this is due to the element’s very dispersed amount in the deposit, way below the detection limit of the apparatus.…”

This work presents a study on the influence of biologically relevant ions on the corrosion of zinc (Zn) in physiological fluids. Electrochemical techniques were used to investigate the degradation of pure Zn exposed to different physiological electrolytes containing chlorides, carbonates, sulfates, and phosphates. The corrosion behavior of Zn in the solutions over a 7-day period was also assessed. SEM, EDS, and FTIR were used to analyze corrosion products. With respect to corrosion, the most aggressive ions are chlorides, which induce localized corrosion, while carbonates and phosphates reduce the corrosive attack of the chloride on Zn while inducing uniform corrosion. Sulfates reduce the corrosion rate by disrupting Zn’s passive layer. The overall corrosion rate of Zn changed in each electrolyte depending on the nature of the solution and the corrosion product formed. These findings will be useful in predicting the in-service behavior of future biodegradable Zn medical implants.

“…The reported works carried out to investigate the effect of ac on corrosion of pipeline steel have concluded that pipelines corrode at an accelerated corrosion rate under ac interference. 13–19 The present studies on corrosion of zinc are mainly concentrated on the pitting corrosion of zinc 20,21 and the effects of aggressive anions (Cl − , Br − , I − , , and S 2 − ), 22,23 cations (Mg 2+ , Ca 2+ and Na + ), 24 acid gas (CO 2 and SO 2 ) 25 and the passive film 26–29 on corrosion of zinc. Several works 30–32 were conducted to investigate the coupling corrosion of zinc and carbon steel.…”

Zinc ribbon has been widely used for alternating current (ac) mitigation of pipeline. However, little is known about corrosion of zinc under ac. In this work, the corrosions of zinc under various ac in two scenarios, i.e. with or without direct current (dc) decoupler, were investigated in 4 g L 21 Na 2 SO 4 simulated backfill solution by weight loss tests, low angle X-ray diffraction measurements and electrochemical measurements. It was found that ac accelerated corrosion of zinc dramatically in both scenarios, and it is worth noting that dc density between zinc and pipeline steel increased with ac in the scenario without dc decoupler. Consequently, corrosion rate of zinc was much larger than that in the scenario in which dc decoupler was used. Besides, the charge transfer resistance of zinc decreased considerably due to ac in both scenarios, which would largely increase corrosion rate.
