Special Issue Information
Dear Colleagues,
Laser cladding technology is a new surface modification technology rising with the development of high-power lasers in the 1970s. During its operation, the laser beam rapidly heats and melts the alloy powder or ceramic powder and the substrate surface; as the laser beam moves away, the powder cools to form a surface coating with very low dilution and metallurgical bonding with the substrate material, which can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties.
It is a new in situ manufacturing/repairing technology with high economic benefits, in that it can prepare high-performance alloy surfaces on cheap metal substrates without affecting the properties of the substrate, reducing costs and saving precious and rare metal materials. Compared with built-up welding, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, dense structure, good combination between coating and substrate (which are more suitable for cladding materials), and can change particle size and content to a great extent. Therefore, the world’s advanced industrial countries attach great importance to the research and application of laser cladding technology.
In this Special Issue, we welcome articles that focus on laser cladding technology, including but not limited to: microstructure evolution, products’ mechanical performance, fatigue life, numerical modelling methods, optimization processing design, novel materials design methods and new application fields, etc. We invite you to contribute research that studies the effect of manufacturing on the structure of aluminum alloys and that relates the structure with different properties.

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.
