Special Issue Information

Dear Colleagues,

Laser material processing has a major role in various engineering research and manufacturing industries. This is due to the application of laser energy to modify the properties or the shape of a material. This technology has many advantages, such as tool-less production, high flexibility, superquick production, and a high quality of finished products. Moreover, this method can be applied for a wide range of materials from metal (including stainless steel, aluminum, titanium, or iron) to nonmetals (such as plastics/polymers, composites, graphenes, or adhesives).

Laser processing of thin films is a novel and rapidly expanding field with potential application in various industries, such as electronic products. Therefore, a lot of publications report the effect of laser processes, including welding, deposition, and treatment, on the properties and the microstructure of the films. In particular, some studies investigate the fundamentals of laser interactions with the materials experimentally and give more details on some processes, such as film deposition, annealing, nucleation, and growth as well as localized and selective.  

The journal will publish communications, articles, and reviews that are of high quality, impact, and novelty, as well as being interesting for a wide audience from the scientific and technological communities. Potential topics for this Special Issue include, but are not limited to, the following:

  • Recent developments in laser processing (welding, deposition, treatment, etc.) of thin films;
  • Novel approaches and technologies using the laser process to improve quality and efficiency;
  • Theoretical and experimental research, knowledge and new ideas in thin-film processes using a laser source;
  • Mathematical modeling or numerical simulation to predict the optimal operational parameters for laser processing of thin films;
  • The latest development of test methods, including mechanical and microstructural analysis of laser-fabricated or -treated thin materials.

The Coatings journal by MDPI is a peer-reviewed, open access, and online-only journal.

The process parameters of laser cladding have a significant influence on the forming quality of the coating. This research investigates the relationship between input process parameters (laser power, scanning speed, pre-placed thickness) and output responses (height, width, dilution rate) of Mo2FeB2 coating through sensitivity analysis. The microstructure and properties of selected coatings were analyzed to discuss the corresponding relations. The results showed that the laser power positively affected the coating width and dilution rate, while negatively affecting the coating height. The scanning speed had a negligible effect on the height and dilution rate. The pre-placed thickness had a positive influence on the height and width; it negatively affected the dilution rate. Based on the sensitivity analysis, the thickness of the pre-placed coating determined the most sensitivity to the height. The sensitivity of the width to laser power was the highest among all parameters. The sensitivity of dilution rate to laser power and pre-placed powder thickness showed a noticeable impact. When the scanning speed was 3 mm/s, the forming quality of coating had a significant sensitivity for a higher or lower laser power (1.5, 2.1 kW) and higher or lower powder thickness (0.8, 1.2 mm). The analysis of microstructure and microhardness of Mo2FeB2 coating indicates that the Mo2FeB2 coating improves substrate properties. The microhardness of the Mo2FeB2 coating was 4–6 times that of the substrate, and the highest microhardness could be obtained by 1.5 kW laser power, 3 mm/s scanning speed, and 1.2 mm powder thickness from the sensitivity analysis results.
