Special Issue Information

Dear Colleagues,

The last couple of decades have brought exciting breakthroughs in the utilization of plasmas to design a diverse range of materials and engineered coatings and interfaces. Today, plasmas are widely employed to modify the surface properties of materials without changing their bulk properties. Examples include sensing, the food and packaging industry, medicine, agriculture, printable electronics, energy harvesting, transportation, and applications in numerous areas of everyday life. Many of these materials, coatings, and interfaces are unique and cannot easily be derived by conventional techniques. From this point of view, this Special Issue aims to bring together the latest advances in the fields of plasma engineering of interfaces, coatings, and structures and their application in various fields. We invite investigators to contribute original research articles, as well as review articles that will inspire research towards the next generation of plasma-derived materials and their applications. Potential topics include, but are not limited to:

- chemical and physical reactions in thermal and non-thermal plasmas;

- modeling of plasmas and their interaction with materials;

- plasma-assisted thin film deposition;

- plasma etching and surface engineering;

- plasma electrolytic oxidation (PEO);

- plasma texturing of surfaces;

- plasma functionalization of surfaces;

- plasma-derived nanoscale coatings;

- applications of plasma-derived materials and engineered surfaces;

- properties and performance of plasma-sprayed coatings: corrosion, mechanical, tribological, catalytic, biomedical, and/or electric evaluation.

Iron-based amorphous coatings are getting attention owing to their attractive mechanical, chemical, and thermal properties. In this study, the comparative analysis between high-velocity oxy-fuel (HVOF) and atmospheric plasma (APS) spraying processes has been done. The detailed structural analysis of deposited coatings were studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Mechanical and electrochemical properties were investigated by using micro-Vickers hardness testing, pin-on-disc tribometry and potentiodynamic analysis. The microstructure comparison revealed that HVOF-coated samples had better density than that of APS. The porosity in APS-coated samples was 2 times higher than that of HVOF-coated samples. The comparison of tribological properties showed that HVOF-coated samples had 3.9% better hardness than that of coatings obtained via APS. The wear test showed that HVOF-coated samples had better wear resistance in comparison to APS coatings. Furthermore, the potentiodynamic polarization and electrochemical impedance spectroscopy showed that the HVOF-coated samples had better corrosion resistance in comparison to APS-coated samples.
