“…Indeed, some authors show that winds can transport sand and other hard particles and then provoke accelerated metal erosion or corrosion-erosion effects. [36][37][38] System 2 seems to be site dependent. Indeed, the propagation rate varying between 10 and 14 mm²/year is measured in Bohus-Malmön, Qingdao, Dubai, and Daytona.…”

Cr‐free paints applied on different aluminum alloys were exposed for 5 years at different atmospheric weathering sites worldwide. By image analysis, the extent, and the type of corrosion (filiform or blistering) were determined after 1, 2, and 5 years. In that way, it was possible to rank the different systems as a function of their resistance to corrosion. The kinetics of degradation of each system at all sites was also determined. From the results, it is shown that the kinetics of degradation is system dependent. It is also shown that it is the combination of several climatic parameters which contributes to the corrosivity of the site and not only one single parameter such as chloride deposition, relative humidity, and so on.

“…The test setup used in this work is schematically presented in Figure 1(a). The rotation disc system (Yunchi, China) is same as the one used in previous studies [23,34]. The diameter and the thickness of the rotation disc are 60 and 20 mm, respectively.…”

“…It is reported that the erosion steel loss of carbon steel is mostly induced by corrosion-enhanced erosion when the flow velocity of sea water is lower than 5 m s −1 [18]. The surface hardness degradation caused by anodic dissolution is the basic requirement for the initiation of obvious erosion in this case [23,24]. It is normally believed that CP could effectively inhibit both corrosion and erosion of carbon steel in sea water of a relatively low flow velocity [25,26].…”

In this work, the influence of sand impingements on cathodic protection (CP) of marine carbon steel in natural sea water was studied in comparison with the CP performances in static and flowing sea water without sand particles. Results show that the propagation of local active anodic dissolution at the steel inclusions could be totally inhibited by providing sufficient cathodic current in the sea water free of sand particles. However, the local 'CP shielding', potential fluctuation and sand impingements would enhance the anodic dissolution at inclusions, thus leading to the occurrence of erosion-corrosion under CP. The negative shift of the CP potential could not retard the propagation of erosion-corrosion pits under sand impingements. The synergy of erosion and corrosion might result in long-term failure of local CP.

A partial pre-rusted wire beam electrode (WBE) was designed to study the influence of the rust layer on rebar corrosion in the carbonated simulated concrete pore solution (SCPS). The results show that the passive film generated on the pre-rusted steel area is more fragile than that formed on the fine polished steel area in carbonaceous media. Nevertheless, the pitting corrosion resulting from the presence of chloride ions still tends to occur on the fine polished steel surface due to the local acidification process being hindered by the rust layer. The rust layer could play a more important role than the passive film in inhibiting the initiation of chloride-induced corrosion on rebar. The expansion path of the corrosion product would be blocked by the rust layer, leading to the pit propagating in the fine polished region. Furthermore, the growth of pitting corrosion is greatly accelerated due to the catalytic cathodic reaction of the rust layer.
