Special Issue Information

Dear Colleagues,

Surface integrity, materials control, design variable constraints, reliability, maintainability, production sustainability, and cost factors are some of the issues that are still limiting the total inclusiveness of surface modification in many industries.

Metallic component characteristics have been laser-surface-modified in the past using composite coatings such as metal matrix composites in a bid to enhance the surface properties. Instead of tampering with the whole microstructure of metallic components base structure, direct laser surface modification can be used to target and solve a particular problem. This will result in extended application of metallic components. The enhancement of components’ service life span can be achieved by fabricating metallic composite coatings. When there is failure of material due to exposure to environmental conditions, it can either be repaired or replaced for extended service life span. Laser surface modification techniques are another way of enhancing metallic materials’ properties compared to conventional methods. The direct laser surface modification technique has been identified as one of the most promising areas for producing engineering components. The process parameters used for these techniques have an impact on the structure and mechanical properties of a finished product. Quality parts cannot be produced until deep understanding of the technology is inculcated and the materials design is well understood. These require all the aforementioned process parameters to be optimized and materials selection decision making needs to be carried out right.

For laser surface modification of metallic materials to exhibit excellent properties, swift heating and solidification must play a part in the enhanced properties as a result of the complex nature of the process. This is because properties of materials are affected by temperature distribution.

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 2000 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.
