Hot Corrosion and Oxidation of Alloys

Dear Colleagues,

The hot corrosion and oxidation of metals and their alloys are complex phenomena involving the high-temperature (above 500 °C) transformation of metallic materials into oxides, sulphides, or chlorides. Oxidation processes are mainly considered when exposing alloys to air, oxygen, or steam, followed by the formation of oxide layers sometimes accompanied by nitrides. Hot corrosion is an accelerated oxidation that occurs when materials are exposed to air contaminated with sulphurous gases from the combustion of fossil fuels. The interaction between sulphurous gases and sodium chloride usually presents in air close to seawater, resulting in the deposition of sodium chloride and sodium sulphate salt onto the surface of the material, which significantly increases the corrosion rate, especially when the salts are in a liquid state. Therefore, the hot corrosion and oxidation of alloys are affected by many factors, including temperature, atmosphere composition, alloy composition, slat deposit, and the presence of protective coatings as well as substrate surfaces. The study of oxidation and hot corrosion processes mainly concerns alloys applied in gas turbines, aero engines, furnaces, and chemical apparatus used in different processes, e.g., carburization, chlorination, and acid production. The most popular alloys that can be used in such applications are superalloys, stainless steels, titanium alloys, as well as high-entropy alloys. Therefore, we are pleased to invite researchers to contribute to a Special Issue entitled “Hot Corrosion and Oxidation of Alloys”, intending to be a comprehensive review on metals and their alloys working at high temperatures in an oxidizing atmosphere, sometimes in the presence of salt deposits or severe gases. We also welcome submissions of original research papers, short communications, and reviews related to the Special Issue topic.

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 250 words) can be sent to the Editorial Office for assessment.

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. Crystals 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 2100 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.
