Make sure you thoroughly understand the following essential ideas. It is especially important that you know the precise meanings of all the highlighted terms in the context of this topic. Corrosion can be defined as the deterioration of materials by chemical processes. In a sense, corrosion can be viewed as the spontaneous return of metals to their ores; the huge quantities of energy that were consumed in mining, refining, and manufacturing metals into useful objects is dissipated by a variety of different routes. The economic aspects of corrosion are far greater than most people realize; the estimated cost of corrosion in the U. Utilities, especially drinking water and sewer systems, suffer the largest economic impact, with motor vehicles and transportation being a close second.

Corrosion Science

The common understanding of aqueous CO 2 corrosion mechanism considers carbonic acid as an electroactive species. The direct reduction of carbonic acid on a steel surface is believed to be the cause of the higher corrosion rates of mild steel, as compared to that observed in strong-acid solutions with the same pH. However, in-depth quantitative analyses based on comprehensive mechanistic models, developed in recent years, have challenged this idea. In an attempt to provide explicit experimental evidence for the significance of direct reduction of carbonic acid in CO 2 corrosion of mild steel, the charge transfer controlled cathodic currents in CO 2 saturated solutions were investigated in the present study. The experiments were conducted on three different surfaces: Type L stainless steel, pure iron, and API 5L X65 mild steel, in order to examine the possible effect of alloying impurities on the kinetics and the mechanism of cathodic currents. This confirmed that the direct carbonic acid reduction was not significant at the conditions covered in the present study, and its sole effect was to buffer the hydrogen ion concentration.


Corrosion is a chemical or electrochemical oxidation process, in which the metal transfers electrons to the environment and under- goes a valence change from.


16.8: Electrochemical Corrosion

It seems that you're in Germany. We have a dedicated site for Germany. The second edition of this textbook includes refined text in each chapter, new sections on corrosion of steel-reinforced concrete and on cathodic protection of steel reinforced bars embedded in concrete, and some new solved examples.

We apologize for the inconvenience...

In general corrosion is the reaction of a material with its environment. This leads to a change, and thus affecting the functionality of the material.

EDU - ЕТ? - спросила Сьюзан. У нее кружилась голова.  - Энсей Танкадо и есть Северная Дакота. Это было непостижимо. Если информация верна, выходит, Танкадо и его партнер - это одно и то же лицо.

Тебе надо лечиться от паранойи. В трубке повисло молчание. - Мидж… - Джабба попробовал извиниться.  - Позволь мне объяснить.

Это сложнейшая работа, заключающаяся в постоянном отсеивании лишнего, но она вполне выполнима.

 Примите мои поздравления, мистер Беккер. Мне сказали, что вы сегодня отличились. Вы позволите поговорить с вами об. Беккер заколебался.

Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился. - Какие-то проблемы? - спросил лейтенант. - Да, - сказал Беккер.

 - Вводите ключ и кончайте со всем. Джабба вздохнул. На сей раз голос его прозвучал с несвойственным ему спокойствием: - Директор, если мы введем неверный ключ… - Верно, - прервала его Сьюзан.  - Если Танкадо ничего не заподозрил, нам придется ответить на ряд вопросов. - Как у нас со временем, Джабба? - спросил Фонтейн.

 Хотела бы, Джабба, но я должна следить за своей талией. - Ну да? - Он хмыкнул.  - Давай я тебе помогу.

Странные очки, подумал Беккер, увидев проводок, который тянулся от ушных дужек к коробочке, пристегнутой к брючному ремню. Но он настолько устал, что ему было не до любопытства. Сидя в одиночестве и собираясь с мыслями, Беккер посмотрел на кольцо на своем пальце.

 Ассоциативный ряд? - по-прежнему недоумевал Дэвид. - Стандартная для АНБ процедура. Мне нужно знать, с кем я имею.  - Глаза ее смотрели сурово.

 - Хейл вроде бы затрубил отбой.  - Теперь это не имеет значения.
