Special Issue Information

Dear Colleagues,

We are pleased to announce the Special Issue, “Research on Corrosion Behavior of Metallic Material”, which will focus on various corrosion processes in metallic materials. The scope of this issue includes, but is not limited to, corrosion phenomena at high temperature, exposure to body fluid, immersion, and fog in an aggressive environment. Additionally, the influence of the metallic material fabrication on corrosion behavior will be a key topic in this Special Issue, including laser processing, additive manufacturing, welding, soldering, anodising, and surface treatment. This issue will also feature studies exploring the development of innovative electrochemical techniques to characterize the corrosion, such as electrochemical impedance spectroscopy, the Mott–Schottky method, and electrochemical noise. Furthermore, research is being conducted on novel corrosion inhibitors, including natural inhibitors and rare-earth inhibitors. In addition, the corrosion model studies will also be considered for this Special Issue. 

Dr. Juan Ignacio Ahuir-Torres

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. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Additive manufacturing (AM) enables the fabrication of complex geometries and high-performance alloys such as 17-4PH stainless steel. However, the surface defects inherent to AM components compromise corrosion resistance. The post surface treatment can reduce and eliminate these defects. This study examines the effect of centrifugal mass finishing on the corrosion behaviour of 17-4PH stainless steel produced by AM. Corrosion behaviour of the samples in a 0.6 M NaCl solution is assessed using electrochemical technique testing, including asymmetry electrochemical nose, potentiodynamic polarisation curves, electrochemical impedance spectroscopy, and Mott-Schottky. All electrochemical testing were conducted in concordance with the specifications of ASTM standards. The electrochemical impedance spectroscopy were performed over period ranging from 2 h to 96 h with intervals of approximately one day. Finished specimens exhibit significantly improved corrosion resistance compared with as-built counterparts. Notably, the polished surfaces demonstrate spontaneous oxidised layer recovery between −0.297 V and 0 V, indicative of the enhancement of the protection during early immersion stages. This behaviour is attributed to surface modifications induced by the finishing process, including reduced roughness in 78% and imperfections. These findings highlight the importance of optimising post-processing protocols to improve the durability of AM stainless steels in aggressive environments. Full article
