Laser Technology of Thin Film and Coatings

Dear Colleagues,

Laser metal deposition, as an advanced material surface modification technology, provides a feasible solution for the protection and remanufacturing of damaged parts. This method is usually used to generate more functional protective layers and repair damaged or worn surfaces. This method can form a metallurgical bond with a high bonding strength and low dilution rate between the cladding layer and the base material, thereby enhancing the corrosion resistance and wear resistance of the metal, which can not only reduce production costs and extend replacement cycles, but also avoid the production technology problems of difficult-to-process materials in extreme thermal, mechanical, chemical, and nuclear environments. However, the performance of laser metals and alloy deposition coatings under these extreme conditions must be understood.

In addition, defects such as cracks and pores in the coating also hinder the further promotion and application of this technology. Therefore, it is necessary to explore the mechanism and inhibition method of cracking in the laser metal deposition layer.

  This scope of this Special Issue will serve as a forum for papers in the following concepts:

• Coatings produced by laser processes;
• Performance of coating and film in extreme thermal, mechanical, chemical, and/or nuclear environments;
• Microstructure evolution and associated changes in mechanical properties associated with exposure to extreme conditions;
• Computer modeling, simulation to predict coating properties, performance, durability and reliability in service environments;
• A detailed characterization of cracking mechanisms in coatings during laser processing;
• A fundamental understanding of cracking mechanisms to control or eliminate cracking in the laser metal deposition process.

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. Coatings 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.
