Special Issue Information

Dear Colleagues,

In the age of rapidly advancing industries, the importance of protecting various components from surface damage, whether it be through chemical and/or mechanical means, has become a critical issue. To combat these costly issues, various coating technologies have been applied, whether it be through deformation-, thermal-, or laser-based means. Examples of such coating technologies include thermal spraying (e.g., high-velocity oxygen fuel (HVOF) coating, plasma spraying (PS), atmospheric plasma spraying (APS), etc.), kinetic spraying (e.g., cold spraying (CS), aerosol deposition (AD), etc.), and laser powder additive manufacturing (e.g., powder bed fusion (PBF), selective laser melting (SLM), etc.). When these coatings are applied, various surfaces can effectively be protected in extreme high-temperature, high-stress, corrosive, oxidative, erosive, and wear-based environments. Given the rapid advancements in these fields, an increasing number of industries are considering these technologies as a reliable alternative to other surface modification processes.

This Special Issue invites researchers within this field to submit articles in order to contribute their findings regarding the aforementioned topics (but not limited to these subjects). Research pertaining to the characterization and formulation of powder feedstocks, their coating deposition, and their performance (both in their pre-processed and post-processed conditions) are welcomed. We highly encourage authors to submit both scientific research articles and collective reviews to our Special Issue.

The topics of interest in this Special Issue include, but are not limited to:

  • Laser additive manufacturing: direct laser metal sintering (DMLS), electron beam melting (EBM), selective laser melting (SLM), selective laser sintering (SLS), laser metal fusion (LMF), laser engineering net shape (LENS), laser metal deposition powder (LMD-p), direct metal deposition (DMD), laser cladding (LC), laser-based metal deposition (LBMD), and laser freeform fabrication (LFF);
  • Thermal spraying: high-velocity oxygen fuel (HVOF), high-velocity air fuel (HVAF), plasma spraying (PS), and flame spraying (FS);
  • Kinetic spraying: high-pressure cold spraying (HPCS), low-pressure cold spraying (LPCS), and aerosol deposition (AD);
  • Metal matrix composites;
  • High-temperature, oxidative, dry, lubricated, and corrosive-wear;
  • Characterization, microstructure, and mechanical properties;
  • Equipment and powders;
  • Effect of pre- and post-treatments (e.g., friction stir processing (FSP), laser shock peening (LSP), laser melting (LM), shot peening (SP), and thermo-mechanical treatments);
  • Industrial applications;
  • Mechanical performance.

A unique controlled laser head with an adaptive module was developed to stabilize the trajectory of movement. The scientific and practical problem of developing a technology for restoring the inner surface of a small diameter up to 44 mm was solved by the introduction of a laser head. Adhesion was achieved by moving the laser along the vectors, forming a regular pyramid with opening angles at the top. High physical and mechanical properties of the restored pump surface were achieved by the laser technology when spraying powder composition 15Cr17Ni12V3F35ZrO2. The optimal values of the microhardness of the coating of 5000 MPa were achieved due to the optimal transition melting zone of 0.8 ÷ 1.45 mm; the laser radiation power density of 3 × 105 W/cm2; and the diameter of the focus spot of the laser beam of up to 1.3 mm. High corrosion resistance and tribology were achieved by an optimally matched distance of 10 ÷ 15 mm and a surfacing speed of 15 mm/s. Homogeneous spheroidized particles of the material were observed in the martensitic phase of the structure. The stable compression stresses in the phase structure during the laser deposition of zirconium dioxide were fixed at the level of 1.0 ÷ 1.5 N/m2, and the compression stresses were at the level of 0.2 ÷ 0.4 N/m2. A multifactorial experiment established the dependence of the coating hardness on the distance to the focal plane and the energy characteristics of the laser source, providing optimal laser parameters (area, pulse power, and duration).
