Thermal Sprayed Coatings

Dear Colleagues,

Thermal spraying has become one of the well-known processing technologies, now used in a wide range of industries, from automotive to medical, chemical and even aerospace, to provide wear and corrosion resistance, biocompatibility, and thermal insulation (TBC). Its versatility is due both to the multitude of methods and equipment developed since 1909 when Max Ulrich Schoop laid the foundations of this process, and to the variety of materials that can be deposited: ceramics, metals, cermets, and multi-component alloys, in single or multi-layer. The way coatings are formed is unique and is based on the superposition of individual particles that impact and adhere to the substrate, representing the 'bricks' that form the layers. The unique properties of these coatings thus depend on a multitude of working parameters that influence both how the coating adheres to the substrate and how the splats interact with each other. It becomes very clear that the study of splat morphology and particles phase transformations that occur during deposition and rapid solidification is crucial for the understanding of the coating’s formation and behaviour in operation.

For these reasons, I invite you all to contribute with your valuable studies on obtaining, properties and applications, to complete such a complex picture, which will help other researchers and industrial engineers who want to use thermal spray deposited coatings in various applications.

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.
