Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel corrosion of aluminum and aluminum alloys not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
Jul 25, 2020 · However, the passivation layer can be easily penetrated by Cl in marine environment, inducing the pitting corrosion of aluminum alloys . Superhydrophobic surfaces which are prepared by the deposition of low surface energy organics (e.g. acid, silane) have been successfully used for improving the corrosion resistance of aluminum alloys [  ,  ,  ,  ].Cited by: 5Publish Year: 2020Author: Yongkun Qin, Yan Li, Dong Zhang, Ning Xu, Xichang ZhuUnderstanding Aluminum CorrosionJun 27, 2019 · The corrosion attack on aluminum alloys in soil depends on the composition and climatic conditions of the soil. In dry, sandy soil, corrosion is negligible, but in wet, acidic or alkaline soils, the attack may be severe. Most gases, in the absence of water and at or near room temperature, have little or no action on aluminum-base alloys.The Red Sea as a Corrosive Environment: Corrosion Rates corrosion of aluminum and aluminum alloysCorrosion behavior of Al 7075, Al 2024, and Al 6061 in the Red Sea water was studied using weight loss (WL) measurements and potentiodynamic polarization (PDP) technique. The corrosion patterns and corrosion products formed on Al alloys were characterized using optical photography (OP), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). The results showed that WL data were consistent with bimodal model rather than the power law function and the corrosion rates exhibit See more on hindawi corrosion of aluminum and aluminum alloysCited by: 6Publish Year: 2018Author: Aisha H.

Feb 28, 2017 · Corrosion of aluminum is in general associated with the flow of electrons between the anodic and cathodic regions of the material in an electrolyte, as it usually is in electrochemical corrosion of other common metals.Author: Nemanja PavlovicRelated searches for corrosion of aluminum and aluminum aluminum alloy corrosion chartcorrosion resistance of aluminum alloyssteel and aluminum corrosioncorrosion resistant aluminum alloy chartblack corrosion on aluminumcopper on aluminum corrosionwhite corrosion on aluminumtypes of aluminum corrosionSome results are removed in response to a notice of local law requirement. For more information, please see here.Evaluation of epoxy coatings for protecting aluminum improve corrosion resistance, as has been previously established on AA 2024-T3 and magnesium-yttrium alloys (Zhu and van Ooij, 2003; Dingchuan et al., 2012). The Rust-Oleum Specialty Appliance Epoxy was used after the previous two-part epoxy deteriorated in oxalic acid tests and left the aluminum alloy completely exposed to the effects of the acid.
It is the interaction between local cathodes and anodes and the alloy matrix that leads to nearly all forms of corrosion in aluminium alloys. These include pitting corrosion, selective dissolution, trenching, intermetallic particle etchout, intergranular attack and exfoliation corrosion.Corrosion of aluminum and its alloys Monash UniversityT1 - Corrosion of aluminum and its alloys. AU - Scamans, G. M. AU - Birbilis, N. AU - Buchheit, R. G. PY - 2010/12/1. Y1 - 2010/12/1. N2 - Having been discovered some 180. years ago, aluminum has a relatively short history and only recently completed its first century of commercial manufacture.Cited by: 53Publish Year: 2010Author: G.M. Scamans, N. Birbilis, R.G. BuchheitCorrosion of Ferrous Metals, Aluminum, Magnesium Alloys corrosion of aluminum and aluminum alloysThe alloys of aluminum are subject to pitting, intergranular corrosion, and intergranular stress corrosion cracking. In some cases, the corrosion products of metal in contact with aluminum are corrosive to aluminum. Therefore, aluminum and its alloys must be cleaned and protected.
Corrosion is the chemical reaction of a metal, in this case aluminum, with its environment, which leads to the deterioration of the properties of metals, aluminum in this case. Aluminum is a very reactive metal, but it is also a passive metal. This contradictory nature is explainable because nascent aluminum reacts with oxygen or water and forms a coherent surface oxide which impedes further reaction of aluminum Corrosion of Aluminum and Aluminum AlloysAluminum alloys of the 1xxx, 3xxx, 5xxx and 6xxx series are resistant to corrosion by many natural waters. The more important factors controlling the corrosivity of natural waters to aluminum include water temperature, pH, and conductivity, availability of cathodic reactant, presence or absence of heavy metals, and the corrosion potentials and pitting potentials of the specific alloys.See more on totalmateria corrosion of aluminum and aluminum alloysCorrosion of Aluminum and Aluminum Alloys Aluminum has high resistance to corrosion under the majority ofservice conditions, and no colored salts are formed to stain adjacent surfaces or dis colorproducts with which it comes into contact.

Alloys containing 0. 4-1. 2% Mn, 0. 4-0. 8% Fe, 0. 15% Si and some with small amounts of magnesium have been evaluated. Corrosion resistance increases with an increase in the Mn/Fe ratio but corrosion of aluminum and aluminum alloysCorrosion and Protection of Aluminum Alloys in SeawaterCorrosion of aluminum alloys under exposure to one-phase flow, even under highly turbulent conditions, is a mass transfer controlled phenomenon, as will be discussed further. Cavitation, impingement, or multiphase flow is required for erosion corrosion to occur. Under such circumstances, alumi-num alloys are susceptible to erosion corrosion.Chemical Composition and Properties of Aluminum Alloys corrosion of aluminum and aluminum alloys25 rows · Aluminum has good corrosion resistance to common atmospheric and marine 10700.200.250.0410600.250.350.0510500.250.400.0513500.100.400.05See all 25 rows on unitedaluminum corrosion of aluminum and aluminum alloys
