Temperature is expected to play a significant role in the corrosion of iron pipes in drinking water distribution systems. Temperature impacts many parameters that are critical to pipe corrosion including biological activity, physical properties of the solution, thermodynamic and physical properties of corrosion scale, and chemical rates. Moreover, variations in temperature and temperature gradi...

In the present paper the corrosion properties of structured sheet metals were investigated. The aim of this work is to determinate the influence of the structuring process on the corrosion resistance of sheet metals. For this purpose, these sheets were examined by accelerated tests in corrosion chamber. The investigation was carried out using salt spray test. The experiment was conducted for th...

Significant amount of corrosion damage was revealed during recent complete inspections of airplane structures after years of service. The corrosion damage was located inside airplane’s hull and remained undetected until reaching hull’s outer surface. Therefore a demand for means of timely detection and non-destructive evaluation of corrosion damage arose. This work investigates the possibilitie...

Metallic coatings using thermal spraying techniques are widely applied to structural steels to protect infrastructure against corrosion and improve durability of the associated structures for longer service life. The thermal sprayed metallic coatings consisting of various metals, although have higher corrosion resistance, will still corrode in a long run and may also subject to corrosion induce...

LI, CHONG, Ph.D., June 2009, Chemical Engineering Effect of Corrosion Inhibitor on Water Wetting and Carbon Dioxide Corrosion In Oil-Water Two-Phase Flow (198 pp.) Director of Dissertation: Srdjan Nesic The internal corrosion of flowlines and pipelines made from carbon steel is encountered in the oil and gas industry. The corrosion process is primarily associated with the presence of free water...

magnesium alloys as biodegradable materials can be used in body as an implant materials but since they have poor corrosion resistance, it is required to decrease their corrosion rate by biocompatible coatings. in this study, hydroxyapatite (ha) coatings in the presence of an intermediate layer of zrn as a biocompatible material, deposited on az91 magnesium alloy by ion beam sputtering method at...

Ultra-thin graphene coating has been reported to provide considerable resistance against corrosion during short-term exposures, however, there is great variability in the corrosion resistance due to graphene coating in different studies. It may be possible to overcome the problem of hampered corrosion protection ability of graphene that is caused due to defective single layer graphene by applyi...

The corrosion behavior of X80 steel in the presence of coupled coating defects was simulated and studied under the interference of alternating current (AC) in an alkaline environment. The results from electrochemical measurements showed that the electrode potential of the coating defect with the smaller exposed area was lower than that with the larger area, which indicated that the steel with t...

The corrosion behavior of pure Fe under a Na₂SO₄ deposit in an atmosphere of O₂ + H₂O was investigated at 500 °C by thermo gravimetric, and electrochemical measurements, viz. potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and surface characterization methods viz. X-ray diffraction (XRD), and scanning electron microscope (SEM)/energy dispersive spectroscopy(EDS). The...
