Corrosion is all around us and can affect our lives in many ways, because metals are so widely used in our world. Corrosion-related failures in the industries often result in catastrophic failures. Corrosion is not only dangerous, but costly. The cost of corrosion is estimated to be huge and protecting or reducing corrosion is one of the most important problems in engineering. Many attempts hav...

In this paper, the problem of classifying synthetic and natural texture images is addressed. To tackle this problem, an innovative method is proposed that combines concepts from corrosion modeling and cellular automata to generate a texture descriptor. The core processes of metal (pitting) corrosion are identified and applied to texture images by incorporating the basic mechanisms of corrosion ...

Although it is well known that any material degrades faster when exposed to an aggressive environment as well as that "aggressive" cannot be univocally defined as depending also on the chemical-physical characteristics of material, few researches on the identification of the most significant parameters influencing the corrosion of metallic object are available.A series of ancient coins, coming ...

The heterogeneous structure of Al alloys renders them susceptible to localized corrosion due to the different electrochemical properties existing in the Al-rich solid solution matrix and secondary phase particles. The galvanic interactions between these two phases can result in pit formation either through dissolution of the particles or corrosion of the matrix adjacent to the particles. This d...

The novel Cr-containing low alloy steels have exhibited good corrosion resistance in CO₂ environment, mainly owing to the formation of Cr-enriched corrosion film. In order to evaluate whether it is applicable to the CO₂ and H₂S coexistence conditions, the corrosion behavior of low-chromium steels in CO₂-H₂S environment with high pressure and high temperature was investigated using weight loss m...

For liquid breeder blanket system using molten salts, tritium barrier, anti-corrosion barrier, tritium recovery system and heat exchanger make important roles. Especially in the heat exchanger, the tritium permeation from primary coolant loop to secondary coolant loop must be inhibited by the tritium barrier for safety. To develop it, it is essential to optimize chemical stability of the barrie...

The corrosion behavior of both tin-plated carbon steel and aluminum (Al 1100) in NaCl solutions were studied using electrochemical impedance spectroscopy (EIS). The study objectives were to compare their corrosion behavior in concentrated brine solution, establish the equivalent electrical circuit diagrams of their corrosion phenomena, and consequently develop steady-state corrosion models for ...

Corrosion is the process of degradation or failure of a material resulting from a chemical reaction between the material and its surrounding environment. It is an indispensible research area in material science and engineering, because corrosion resistance characterizes the stability or durability of a material, which is one of the most important material performances in application. Compared w...

The objective of the work was to undertake a literature review on the subject of corrosion inhibition in the offshore oil and gas industry to understand the current issues. The application of chemical corrosion inhibitors can significantly reduce the rate of corrosion of carbon steel pipelines due to the presence of CO2 and/or H2S. An inhibited corrosion rate of 0.1 mm/year can typically be ach...

Recent advances in characterization tools, computational capabilities, and theories have created opportunities for advancement in understanding of solid-fluid interfaces at the nanoscale in corroding metallic systems. The Faraday Discussion on Corrosion Chemistry in 2015 highlighted some of the current needs, gaps and opportunities in corrosion science. Themes were organized into several hierar...
