“…Other articles focused the attention on the corrosion of stainless steel in ethanol‐containing gasoline mixtures as a function of H 2 O, chloride, and acetic acid contaminant content evidencing that Cl − ions and H 2 O are relevant corrosion activators in EtOH/gasoline mixtures . In order to reduce corrosion problems in distribution and storage systems, the legislation limits the water content . In particular, water is normally a low content contaminant in commercial fuels such as gasoline and it was evidenced that low water content decreases the passivation stability and increases the localized corrosion sensitivity …”

Mechanism of pitting corrosion of different Al alloys in anhydrous ethanol have been evidenced and discussed. Corrosion tests were carried out in an autoclave placed in a temperature controlled oil bath. It was observed that aluminum alloy characteristics greatly influence pitting activation and propagation mechanisms and morphologies. Better electrochemical stability was observed for AA6082 alloys. Instead intense corrosion phenomena were observed on AA5754 and AA5083 samples. Based on experimental results, a schemed model of the degradation stages of aluminum alloys surface during dry corrosion was proposed.

“…A recent study [37] investigated the corrosion of martensitic stainless steel in ethanol-containing gasoline mixture as a function of water, chloride and acetic acid concentrations. The results obtained showed that, water and chloride ions (Cl − ) are the primary corrosion causing factors in EtOH/gasoline mixtures; critical water Figure 5.…”

Nowadays, the use of liquid fuels is prevalent in the transport sector due to ease of storage. There are two different fuel types namely, fuels obtained from fossil resources and biofuels made from renewable resources. Typical biofuels in industry use include pure plant oil (PPO), biodiesel, ethyl tertiary butyl ether (ETBE), biobutanol and fuel ethanol. Studies carried out have shown that fuel ethanol can substitute petrol. In addition, ethanol can be blended with gasoline at any ratio depending on the circumstances and the desired fuel. Typical fuel ethanol blends in use are: E5, E10, E20, E25, E70, E85, E95 and E100. Remarkably, there have been evidences of stress corrosion cracking (SCC) of steel storage tanks and associated piping used in fuel ethanol service during the past decade. This chapter is therefore, centered on a description of structural integrity issues related to metallic and nonmetallic materials in fuel ethanol environments. Prior research on the corrosion and stress corrosion cracking behavior of ethanol-gasoline blends are also reviewed.

“…5.8 shows the optical images of the as-printed and heat-treated L-PBF samples taken before and after corrosion tests. Regular large pores were observed on the metal surface following the breakdown potential, indicative of pitting corrosion [60]. No intergranular cracking corrosion was observed in this study.…”
