Corrosion is a natural process that deteriorates materials, commonly metals, due to chemical or electrochemical reactions with their environment. It's a significant concern across various industries, including infrastructure, manufacturing, and transportation. The effects of corrosion can range from minor aesthetic damage to catastrophic structural failure, leading to enormous economic costs and safety hazards.
Several factors influence corrosion, including environmental conditions such as moisture, temperature, pH levels, and the presence of corrosive agents like oxygen, sulfur compounds, and salts. Additionally, the material's composition and microstructure play crucial roles in its susceptibility to corrosion.
To mitigate corrosion and prolong the lifespan of materials, various protection methods are employed:
Barrier Protection: This involves applying coatings or barriers to physically isolate the material from its environment. Common barrier materials include paints, polymer coatings, and enamels. These coatings create a protective layer that prevents corrosive agents from reaching the underlying material.
Cathodic Protection: This method involves making the metal to be protected the cathode of an electrochemical cell, thus reducing its corrosion rate. Cathodic protection can be achieved through sacrificial anodes, where a more reactive metal (such as zinc or magnesium) is connected to the metal to be protected, sacrificing itself to protect the base metal.
Anodic Protection: Conversely, anodic protection works by polarizing the metal to be protected to make it the anode in an electrochemical cell. This method is suitable for metals that exhibit passivity, such as stainless steel. By maintaining the metal in its passive state, its corrosion rate is significantly reduced.
Inhibitors: Corrosion inhibitors are chemicals that are added to the environment surrounding the metal to reduce its corrosion rate. Inhibitors work by adsorbing onto the metal surface, forming a protective layer that blocks corrosive agents from reaching the metal. Common inhibitors include organic compounds, chromates, and phosphates.
Alloying: Alloying involves mixing the base metal with other elements to improve its corrosion resistance. For example, stainless steel contains chromium, which forms a passive oxide layer on the surface, protecting the underlying metal from corrosion.
Design Modification: Sometimes, corrosion can be mitigated through design modifications that minimize exposure to corrosive environments or improve drainage to prevent the accumulation of moisture.
Each protection method has its advantages and limitations, and the choice of method depends on factors such as the material, the environment, cost considerations, and the required durability. In many cases, a combination of protection methods may be employed to provide optimal corrosion resistance.

Corrosion Basics.pdf
Corrosion is the deterioration of a material due to a reaction with its environment. Metals corrode through an electrochemical process where the metal oxidizes, releasing energy added during its production. Corrosion occurs via the formation of an electrochemical cell, requiring an anode, cathode, electrolyte, electrical connection, and potential difference. The thermodynamics of corrosion can predict if a reaction is possible based on its change in Gibbs free energy. Kinetically, corrosion rates can be estimated using Faraday's law relating current over time to mass lost. Common factors like environment, metal properties, and geometry can influence corrosion behavior and rates.

Introduction One of the critical problems that affect the.pdf
The document discusses irradiation-assisted stress corrosion cracking (IASCC) in austenitic alloys used in light water reactors. It summarizes that IASCC is caused by physical changes to the microstructure from radiation, like hardening and radiation-induced segregation. Radiation hardening and segregation at the grain boundaries lead to chromium depletion, reducing the ability of the alloy to form a protective oxide layer and increasing susceptibility to cracking. The document also examines how the irradiated microstructure evolves over time and dose, forming defect clusters, dislocation loops, and radiation-induced segregation. Increased yield strength from these microstructural changes contributes to higher IASCC susceptibility.

This document describes research into tungsten allylimido complexes as single-source precursors for tungsten nitride (WNx) and tungsten carbonitride (WNxCy) thin films deposited by chemical vapor deposition (CVD). The complexes Cl4(RCN)W(NC3H5) (3a, R = CH3 and 3b, R = Ph) were tested as precursors. Films deposited below 550°C contained amorphous β-WNxCy, while those deposited at higher temperatures were polycrystalline. Film growth rates ranged from 5 to 10 Å/min between 450-650°C. Cleavage of the N-C imido bond is implicated
Recent advances in the study of biocorrosion an overview iwona b. beech
This document provides an overview of biocorrosion and discusses several key mechanisms. It begins by defining biocorrosion as corrosion influenced by microorganisms or their metabolic byproducts. Several types of bacteria are known to influence corrosion, including sulfate-reducing bacteria, metal-reducing bacteria, and metal-depositing bacteria. Sulfate-reducing bacteria can influence corrosion through the production of corrosive sulfides and other mechanisms. Metal-reducing bacteria can promote corrosion by reducing protective metal oxide films. Metal-depositing bacteria may compromise corrosion resistance by depositing inorganic and organic materials on metal surfaces. Biocorrosion poses significant economic costs across many industries.

Irradiated-assisted stress cracking (IASCC) is the accelerated cracking of alloys in the presence of irradiation in high-temperature water. Physical changes to microstructure caused by radiation, such as hardening and segregation, contribute to IASCC. Radiation induces the depletion of chromium and enrichment of nickel at grain boundaries through radiation-induced segregation. Irradiated microstructures also evolve, with point defect clusters forming at low doses and dislocation loops developing with increasing dose. Both radiation-induced segregation and hardening caused by an evolving dislocation microstructure increase the susceptibility of alloys to IASCC. The study identifies mechanisms of radiation effects on water chemistry and microstructure that influence IASCC.

Corrosion.pptx
Corrosion is an electrochemical process where a metal oxidizes and dissolves into its environment. There are several types of corrosion including uniform corrosion, galvanic corrosion, pitting corrosion, and crevice corrosion. Uniform corrosion proceeds uniformly over the entire metal surface. Galvanic corrosion occurs when two dissimilar metals are electrically coupled in a corrosive electrolyte. Pitting and crevice corrosion are localized forms of attack that can cause perforation. Cathodic protection is a technique to control the corrosion of a metal by making it the cathode of an electrochemical cell.

This document provides an overview of the early history and development of atomic theory in chemistry. It discusses how early Greek philosophers proposed ideas about atoms and the four classical elements. It then describes how alchemy dominated for 2000 years, during which time elements were discovered and mineral acids prepared. The foundations of modern chemistry were established in the 16th-17th centuries through quantitative experiments by Robert Boyle and Antoine Lavoisier's verification of the law of conservation of mass through careful weighing experiments. Lavoisier also discovered that combustion involved oxygen, not phlogiston as previously believed. After 1800, chemistry advanced through quantitative experiments determining chemical compositions and Proust's law of definite proportions.

Corrosion inspection in oil and gas pipeline
This document discusses the causes of corrosion in pipelines in Australia. It identifies three major causes: 1) Pitting corrosion, which occurs when pipes made of ductile iron are buried in soil, damaging the protective oxide scale; 2) Stress corrosion cracking, where cracks nucleate and propagate under tensile stress in a corrosive environment; and 3) Galvanic corrosion, which occurs via ion flow when two dissimilar metals are connected in an electrolyte. Corrosion costs Australia $13 billion annually and has caused major accidents by rupturing gas pipelines. Identifying the causes of corrosion is important for reducing hazards and costs to the oil and gas industry.

Monitor indicators of genetic diversity from space using Earth Observation data
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.
