Summary:Title screen
The interest in high-entropy materials is constantly growing since their predicted properties can help to overcome current limitations in different application areas. Despite the number of modeled and calculated high-entropy compounds, there is still a problem with their effective synthesis in the forms of bulk products and coatings, which prevents unambigous determination of their predicted properties. We develop and demonstrate a new method for preparing high-entropy carbide and carbonitride coatings of IV-V transition metal compounds, using (TiZrNbHfTa)CxNy as an example. The developed technique based on the application of a high-speed arc discharge plasma jet leads to the synthesis of a high-entropy carbide TiZrNbHfTaC5 coating and corresponding carbonitride coatings with a thickness of up to 20 μm. The results of studying the physical and mechanical properties of synthesized high-entropy coatings generally confirm the predictions of the preliminary modeling in terms of mechanical properties. Although they are superior in hardness (∼32 GPa vs. 25 GPa). In combination with high oxidation resistance (up to 700 °C), this indicates the possibility of applying such materials not only to creating heat-resistant products, but also significantly strengthening them. The implications and significance of this work extend far beyond the results shown here, as it opens the door to synthesizing many functional high-entropy coatings with different compositions to investigate their properties and performance
