Abstract:

High entropy-based materials in the form of thin films have been of growing interest recently for surface engineering applications due to their exceptional properties including high hardness, superior resistance to oxidation and corrosion, improved thermal stability, and high hydrophobicity. Sputter deposition of thin films comprised of several elements typically requires the use of targets containing multiple elements, making both the chemical composition and microstructure of the resulting films strongly dependent on the process parameters. Therefore, this thesis investigates the growth mech

Abstract:

The investigation of high-entropy alloys (HEAs) has revealed many promising properties. HEAs with a high share of Al and Ti are suitable for the formation of lightweight materials. Investigations of the alloy system AlCoCrFeNiTi showed high strength, hardness, ductility, and wear resistance, which makes this special alloy interesting for surface engineering and particularly for thermal spray technology. In this study, the suitability of inert gas-atomised HEA powder for high-velocity-oxygen-fuel (HVOF) thermal spray is investigated. This process allows for high particle velocities and comparat

Abstract:

Ti-V-Zr-Nb-Hf metallic and nitride films were deposited by filtered vacuum arc plasma from a single equiatomic HEA cathode. The composition, microstructure, mechanical properties, thermal stability and corrosion properties were investigated. The deposited metallic film has a two-phase structure with bcc and hcp-lattice. The nitride films were found to have only an fcc structure. All coatings have nano-grained structures, with grain sizes 5 nm for metallic and 36 nm for nitride. The nitride coatings have a compressive stress of around – 12,5 GPa, high hardness ~ 40 GPa and elastic modulus

Abstract:

In this work was shown the high stability of the single-phase structural state of high entropy alloy of Ti-V-Zr-Nb-Hf system in a vacuum-arc method of obtaining of coatings based on it. In the process of deposition single-phase high entropy coatings with bcc-lattice which characterizes the cast state are formed in vacuum, and upon obtaining in a nitrogen atmosphere single-phase nitride superhard coatings based on fcc-metal lattice are formed. Such a stability of structure of multi-element alloy to high temperature evaporation and deposition from high-energy plasma flows allows to use the

Abstract:

Multi-component coatings and high entropy alloys have in recent years attracted great interest for research, since they have shown to exhibit properties greater than the com- ponents of their parts. Today’s climate challenges requires transitioning from fossil fuels to renewable energy sources which demands use of new technology and new innovations. The hydrogen fuel cell is a technology which produces no carbon emissions, and the drive for innovation has led researchers to apply multi-component (high entropy alloys) coatings to invent the next generation hydrogen fuel cells and help the trans

Il est nécessaire de développer des revêtements sans cobalt possédant une bonne résistance à l’usure afin de remplacer les alliages de type stellite® qui sont utilisés dans les centrales nucléaires. En effet, les débris de cet alliage sont activés sous flux neutronique et forme du 60Co, un isotope radioactif susceptible de contaminer le reste de l’installation. Les matériaux sans cobalt, base nickel ou base fer, proposés pour le moment ne présentent pas des propriétés tribologiques concurrentes à celles du stellite®.

Full text

Abstract:

High entropy alloys (HEA) are metallic compounds containing from 5 to 13 metallic elements in equiatomic ratios. In HEAs, because of the high mixing entropy, formation of brittle intermetallic phases is usually avoided and simple solid solutions are rather stabilized (BCC and/or FCC). This study used molecular dynamics (MD) package LAMMPS to simulate the AlCoCuFeNi nanoparticle (NP) crystallization.
