sulfide production has been one of the most important problems in sewage collection systems that came to be known as an important factor of corrosion in concrete sewerage systems since early 1900. the emission of hydrogen sulfide gas in sewerage conduits creates problems including biological corrosion of concrete, release of repulsive odors in the city environment, as well as the potential dang...

Corrosion in natural seawater is difficult to simulate a laboratory due the slow rate and complexity of corrosion process which involves multiple influential factors. This paper aims explore quantitative effect environmental factors on find best experimental conditions represent actual environment have acceleration effect. A new framework followed this consists three parts: design experiments, ...

A Fenton reaction and a corrosion inhibition strategy were designed for enhancing the polishing rate achieving corrosion-free Ge1Sb4Te5 film surface during chemical-mechanical planarization (CMP) of three-dimensional (3D) cross-point phase-change random-access memory (PCRAM) cells 3D synaptic arrays. The was conducted with 1,3-propylenediamine tetraacetic acid, ferric ammonium salt (PDTA–Fe) H2...

The present study reveals that the selected plants would exert several benefits by virtue of their antioxidant activity and could be harnessed as antimicrobial, anti-inflammatory and anti-corrosive agents. The aqueous and Ethanol crude extract of Neem, Hibiscus leaves and the mixture of both leaves' extract were screened for their free radical scavenging properties. Free radical scavenging acti...

This work aims at proposing a novel approach to classify acoustic emission (AE) signals deriving from corrosion damage, even if embedded into a noisy environment. Tests involving noise and crevice corrosion are conducted, by preprocessing the waveforms including wavelet denoising and extracting a rich set of features as input of the Random Forest algorithm. To this end, a software called RF-CAM...

This paper studies the corrosion behavior of B10 copper-nickel alloy in marine environment. Accelerated degradation test under marine environmental conditions was designed and performed based on the accelerated testing principle and the corrosion degradation mechanism. With the prolongation of marine corrosion time, the thickness of Cu₂O film increased gradually. Its corrosion product was Cu₂(O...

The corrosion of steel reinforcement in an aging highway infrastructure is a major problem currently facing the transportation engineering community, in particular bridge engineers. In the United States, maintenance and replacement costs are measured in billions of dollars. Further, the use of deicing salts has resulted in steady deterioration of bridge decks due to corrosion. These concerns ha...
