Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to this Special Issue on “Advanced Plasma Surface Treatments and Their Applications in Coating Technologies”. Plasma surface treatments (PSTs) such as nitriding, carburizing, and advanced coatings functionalize surfaces, improving the mechanical, thermal, and corrosion performance of metallic substrates, along with other tailored properties (e.g., biocompatibility, catalysis, antibacterial response, self-lubrication, etc.). These techniques’ extensive applications range from structural components, particularly in the transport sector, to more advanced fields, such as bioengineering. This Special Issue aims to present the state of the art of PSTs for stainless steel and other alloys through a combination of original research papers, short communications, and review articles from leading research groups around the world.

We welcome experimental investigations, theoretical modeling, and computer simulations of kinetic processes and mechanisms involved in PSTs, particularly as they relate to coatings.

In particular, the topics of interest include but are not limited to the following:

  • Fundamental understanding of PST processes;
  • Properties and performance of PST processes;
  • Coating technologies combined with PSTs;
  • Nitriding, carburizing, and other surface treatments during PSTs;
  • Functionalization of PST surfaces;
  • Bio-applications of PST surfaces;
  • Mass-transport processes during PSTs;
  • Modeling and computer simulations of PSTs;
  • Advanced PST processes and their applications.

We look forward to your contributions, as they will help advance the field of plasma surface treatments and coatings.

In plasma-enhanced chemical vapor deposition (PECVD) processes, thin films can accumulate on the inner chamber walls, resulting in particle contamination and process drift. In this study, we investigate the physical and chemical properties of these wall-deposited films to understand their spatial variation and impact on chamber maintenance. A 6-inch capacitively coupled plasma (CCP)-type PECVD system was used to deposit SiO2 films, whilst long silicon coupons were attached vertically to the chamber side walls to collect contamination samples. The collected contamination samples were comparatively analyzed in terms of their chemical properties and surface morphology. The results reveal significant differences in hydrogen content and Si–O bonding configurations compared to reference films deposited on wafers. The top chamber wall, located near the plasma region, exhibited higher hydrogen incorporation and larger Si–O–Si bonding angles, while the bottom wall exhibited rougher surfaces with larger particulate agglomerates. These variations were closely linked to differences in gas flow dynamics, precursor distribution, and the energy state of the plasma species at different chamber heights. The findings indicate that top-wall contaminants are more readily cleaned due to their high hydrogen content, while bottom-wall residues may be more persistent and pose higher risks for particle generation. This study provides insights into wall contamination behavior in PECVD systems and suggests strategies for spatially optimized chamber cleaning and conditioning in high-throughput semiconductor processes.

Grooving or gouging is a process of thermal processing of metals or welded semi-finished products. The gouging process is generally used to process the root of butt welds to remove possible welding defects. The possibility to obtain and characterize the surfaces after manual and mechanized plasma cutting in the field of bridges and viaducts from highways to construction sites in order to increase the quality of butt-welded joints is analyzed in this article. In order to mechanize the process, a linear universal displacement device for welding, cutting, or slitting that ensures the uniform movement of the torch was designed and executed herein. As a result, with the help of this device and the tests performed on a construction steel S355J2 after mechanized plasma cutting, the cut samples obtained facilitated the analysis of the macrostructure and microstructure of the thermally influenced zone and of the intermediate zone between the thermally influenced zone and the base material as well as their hardness. By mechanizing the cutting process, the productivity and quality of the surfaces obtained by this process has increased. The plasma gouging process is an ecological process and by mechanizing it, the manufacturing cost can be reduced. Full article
