Special Issue Information
Dear Colleagues,
Corrosion theory entails that the process involves an anodic reaction. This type of reaction is produced through dissolving metal, which generates electrons. This is further consumed by another process called the cathodic reaction. These two processes balance the charges produced during corrosion.
The electrochemical corrosion of metals occurs when electrons from atoms at the surface of the metal are transferred to a suitable electron acceptor or depolarizer. Water must be present to serve as a medium for the transport of ions. The most common depolarizers are oxygen, acids, and the cations of less-active metals.
Alloy steel is most commonly used to manufacture pipes, especially pipes for energy-related applications. It is also used in the manufacturing of heating elements in appliances like toasters, silverware, pots and pans, and corrosion-resistant containers.
Smaller items such as screws, nails and bolts made of alloy steels are used in the building and construction industry. Bridges use special alloy steels known as weathering steels. These provide enhanced protection from corrosion because of the presence of nickel, copper and chromium as alloying elements.
Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets.
Alloys have different properties to the pure metal components. For any particular use, an alloy is matched that has the most suitable range of properties.
Aluminum and copper are useful metals. This table shows examples of common alloys that contain these metals:

Alloys and steel undergo corrosion in various environments. This corrosion can be controlled by various methods, such as the use of corrosion inhibitors , painting, cathodic protection etc.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
