Wear, Corrosion and Fatigue Behavior of Ni-Based Superalloys Coatings Deposited via Cold Spray

Dear Colleagues,

Cold spray technology could change the way that we design and make products. As a coating technology, it solves many of the inconveniences of traditional thermal spraying technologies, such as oxidation and phase transformations. As an additive manufacturing technology, it could be able to produce complex shapes that cannot be produced by traditional techniques. In aeronautics, energy, and many other sectors, many parts produced via cold spray are subject to an environment that can progressively wear out, corrode/erode, or strain the materials until fracture. Generally, Ni-based superalloys exhibit very high corrosion resistance and provide high strength and good machinability. For these reasons, they are increasingly used in modern industry. Therefore, the starting point of this Special Issue is the lack of information about the cold spray technology using Ni-based superalloys powders for wear, corrosion, and fatigue applications. Papers in this Special Issue are focused on how cold spray and Ni-based superalloys can be integrated into different industrial sectors and address the key drivers for innovation.

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.
