Special Issue Information
Dear Colleagues,
The continuous evolution of advanced manufacturing has created a growing demand for innovative surface engineering technologies capable of enhancing component performance without compromising material integrity. Among these, cold gas dynamic spray (commonly known as cold spray) has emerged as a versatile solid-state deposition technique, enabling the fabrication of high-quality coatings and repairs while preserving the original microstructure of the feedstock material. This process is particularly well-suited for temperature-sensitive materials and applications requiring high bond strength, wear resistance, or corrosion protection.
This Special Issue is dedicated to showcasing recent progress and addressing current challenges in cold spray research and applications. It aims to bring together contributions that advance our understanding of process fundamentals, materials behavior, and performance optimization. Topics of interest include, but are not limited to, the following:
• Innovations in cold spray system design and process optimization;
• Development of novel feedstock materials and tailored substrates;
• Integration of cold spray in additive manufacturing and repair strategies;
• Coating–substrate bonding mechanisms and interfacial phenomena;
• In situ diagnostics and real-time process monitoring;
• Industrial case studies and application-driven developments.
Through this collection, we seek to highlight cutting-edge research that pushes the boundaries of cold spray technology and fosters its broader adoption across industries.

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. Materials is an international peer-reviewed open access semimonthly 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.
