Special Issue Information

Dear Colleagues,

Long-lasting materials have become a priority to reduce carbon footprints and mitigate climate change. Raw materials are increasingly scarce, and product manufacturing costs are reaching unprecedented levels. In addition to new technologies with, in most cases, hazardous exposure conditions, the development of new design strategies, prevention methods, and monitoring procedures is required to fight against corrosion. Thus, corrosion control is essential for the goal of a sustainable society.

This Special Issue intends to compile the most recent advances in corrosion research. Contributions from traditional fields such as transport, chemical industry or civil engineering are welcome, but innovative improvements in the areas of additive manufacturing or biomaterials are also sought.

Submissions discussing methods for corrosion mitigation, including environmentally friendly solutions such as high-performance coatings, cost-effective advanced materials, inhibitors, or novel solutions, as well as innovative testing procedures, including sensors or remote monitoring, to reliably assess corrosion behavior and to predict corrosion damage are encouraged.

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. 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.

To address the corrosion protection issues for hot components of high-end equipment in extreme service environments, the C276 alloy coating was deposited on the surface of 304 stainless steel via high-velocity air fuel (HVAF) spraying. The extreme conditions of 1000 °C temperature, an atmosphere containing 6% HCl, and a flow rate of 30 m/s were simulated in the study using a high-temperature airflow corrosion erosion device. The C276 coating and the 304 stainless steel substrates were subjected to a corrosion test for 25 min. The surface phase composition, element distribution, corrosion product characteristics, and cross-section structure of the samples before and after corrosion were systematically analyzed by means of a scanning electron microscope, an energy dispersive spectrometer, and an X-ray diffractometer. The mechanism of high-temperature chlorination corrosion was deduced through thermodynamic and kinetic analysis. The results show that compared with 304 stainless steel, the C276 alloy coating exhibits better corrosion resistance in an extremely high-temperature environment containing HCl, and the average weight gain and growth rate of the corrosion layer were lower. The main corrosion products on the C276 coating surface are Fe2O3, FeO, FeCl2, NiO, and Cr2O3, among which the oxides of Ni and Cr form a continuous and dense protective oxide layer that effectively inhibits the intrusion of corrosive media. The high-temperature HCl corrosion follows the ‘chlorination–oxidation’ cycle mechanism, and Cl2 plays a catalytic role in the reaction and accelerates the corrosion process. Full article
