Special Issue Information
Dear Colleagues,
Although wire arc spraying first came into use 100 years ago, it is still widely applied in workshops and on construction sites all over the world with no alteration to its original general principle: the melting of metal-based wire feedstock by an electric arc and the subsequent spraying of this melt by compressed gas. The use of localized, high arc energy and the lack of necessary fuel gases make conventional wire arc spraying a cost-efficient, easy-to-handle process with the highest deposition rates amongst the thermal spray family processes. Therefore, wire arc spraying was, and still is, a common process of choice for buffer layers, large-area coatings, and on-site applications. In comparison with the powder-processing HVOF and plasma spray processes, however, conventional arc spray coatings generally show higher levels of pores, dissolved gases, and oxides, which are often associated with weak coating adhesion. These challenges of wire arc spraying have been a focus in recent years, due to the optimization of torch designs and adapted spray parameters through improved current sources and new process simulation possibilities, which brought coating quality into regions of high-velocity spray processes. Also, especially driven by the automotive industry, inner-wall spraying processes based on wire arc spraying principles have been developed and successfully applied to products.
This Special Issue of Metals on “Arc-Sprayed Metallic Coatings” attempts to summarize the current state-of-the-art of modern wire arc spray processes and applications in one single release. It will address the applications, materials, coating parameters, torch and nozzle designs, spray processes, process simulations, and pre- and post-treatments and will offer a source of inspiration for further R&D to readers both from academic and business fields.

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.
