The application of various metal, ceramic, or metal–ceramic composite coatings is currently considered as the one of the most effective methods to tailor surface properties of materials to specific requirements for conventional and advanced technological applications. The well-defined surface properties induced by various coating layers can change mechanical (e.g., hardness, fatigue limit, elongation, tensile strength), thermal (e.g., thermal conductivity, expansion), electrical, and many other functional properties of materials (corrosion resistance, hydrophobicity or super-hydrophobicity, wettability, optical properties, etc.) without the necessity of using expensive and time-consuming heat treatments or alloying techniques. Metal coatings are successfully used in photovoltaics, optical, energy conversion, and sensing devices. Ceramic coatings create a barrier on the substrate that separates the material from the corrosive environment, thus enhancing its corrosion resistance. Additionally, the coatings provide better abrasion resistance that makes them extremely robust and ensures a longer life for the coated surface. Moreover, the coatings can modify surface texture for specific needs, enhance wettability/hydrophobicity, provide better wear resistance and thermal/electrical insulation, and improve surface hardness of a given material. Application of various coatings is, therefore, an efficient and affordable method to obtain the desired surface and material properties for a broad range of applications.
In particular, the topics of interest include but are not limited to:
- The effect of thin coatings on mechanical properties of bulk materials;
- New directions in design and production of hard coatings;
- Thermal barrier coating (TBC) to prevent heat loss;
- Smart and self-healing coatings for corrosion protection;
- Super-hydrophobic and self-cleaning coatings;
- High refractive index (HRI) coatings;
- Plasmonic and antireflecting coatings;
- Single and multilayer films;
- Coating methods and technologies.

1. Title: Stiffness analysis of Fe-Al type intermetallic protective coatings (GDS) in Young's modulus tests at temperatures up to 1000 oC

Abstract: The analysis of the stiffness of GDS sprayed FeAl intermetallic coating onto C45 steel in condition after hardening and tempering were presented, in the aspect of the possibility of applying it at elevated temperature and in aggressive corrosive environments. The results of Young's modulus tests, conducted to evaluate the substrate material and the coating applied on it, as a function of temperature up to 1000 oC, confirmed the unique properties of FeAl intermetallic alloys in the context of their application in the power industry. The C45 steel, constituting the base material and the basis for further measurements of the applied coating, was characterized by an average value of the Young's modulus of 210 ±2 GPa, according to data. Under the conditions of temperature change, recorded values of Young's modulus gradually decreased to about 110 GPa at 1000 oC. On the other hand, the sample with the coating of FeAl showed the Young's modulus within 240 ±2 GPa at ambient temperature, decreasing monotonically with heating in the RFDA HT-1050 oven - to about 140 GPa at 1000 oC. Conducted studies of changes of Young's modulus in FeAl coatings as a function of soaking temperature (up to 1000 oC), were allowed determine the value of the pressure present in the contact zone of FeAl powder particles with the steel substrate in the conducted conditions of DGS spraying. This is an important cognitive factor in the analysis of the deformation mechanism and strengthening of nominally brittle intermetallic FeAl phase under the GDS spraying conditions.
