Abstract:

High entropy alloys (HEA) composed of multiple principal elements have attracted wide interest due to superior mechanical and functional properties compared to traditional alloys. HEA alloys expose increased strength and hardness, resistance to oxidation and wear and high temperature stability. Such improvements in properties and features give HEA bulk and coatings a considerable potential for use in a wide range of applications, including those requiring tribological performances. The TriboHEA project aims to develop novel high entropy alloy coatings and coating technology for applications requiring medium/high friction and wear resistant surfaces. Coatings with such tribological characteristics are especially desirable by machine industry for improving the performances and the life time of friction components, such as clutch plates. The projects will focus on the technology development for synthesis of mm-thick HEA coatings to engineer the friction surfaces of clutch plates, subject on which the end-user industrial partner is very interested. The project is planning to advance the coating technology from TRL 3 to TRL 6 by demonstrating the coating performances in the end-user's clutch test rig. To realize that, the TriboHEA Consortium combines one research institution from Romania, one SME from Romania, and the end-user industrial partner from the Basque Country (Spain).

Abstract:

Reducing electromagnetic interference over a broad band of radio frequencies is crucial to eliminate the adverse effects of the increasingly complex electromagnetic environment. Current shielding materials or methods suffer from tradeoffs between optical transmittance and EMI shielding capability. Moreover, poor mechanical flexibility and manufacturing complexity significantly limit their additional applications in flexible electronic devices. In this project a technology will be developed to manufacture transparent conductive thin layer structures with thicknesses of max. 600 nm, with a surface resistance of max. 100 ohms / square for a shielding efficiency of at least 25 dB and for anti-static effect with a surface resistance of maximum 1000 ohms / square, on flexible and rigid transverse substrates for transmissions in visible of at least 80%. Transparent EMI shielding components will be made and tested. The thin layers of electromagnetic protection will be made in the form of a suitable design (eg conductive-dielectric-metal-dielectric) to improve the electro-optical compromises, to obtain a transmittance in the visible spectrum of at least 80% in relation to the substrate and an excellent efficiency. of shielding effect (SE-shielding effectivnes)> 25 dB, over a broadband bandwidth of up to 30 GHz, covering all bands X, Ku, Ka and K. An efficiency of EMI shielding> 30 dB is estimated to be achieved by the overlap of at least two transparent conductive thin layers and could be further improved up to 50 dB by separating two layers with a quarter-wavelength space. High-performance flexible or rigid substrate thin-layer structures have high potential for various applications such as: portable electronics, medical devices and electronic safety zones.

Abstract:

The objective of MONAMIX project is to demonstrate the potential use of mixed REOs with naturally occurring composition, obtained from monazite concentrates, as dopant in the design of high temperature zirconia coatings and sintered materials. The naturally mixed REOs doped zirconia thermal barrier coatings (TBC) will be designed to increase the lifetime of Ni/Cr alloys or reduce the critical raw materials

(CRMs) content in substrate alloys. Sintered natural mixed-REOs doped zirconia will be also designed as solid oxide fuel cells (SOFCs) with controlled ionic conductivity and low REO content. MONAMIX project addresses mainly the topic 2 of ERAMIN II call: Design: 2.1: Product design for increased raw material efficiency and 2.4: Product design for critical materials substitution . A hydro-chemical method for monazite concentrates purification by selective leaching and their usage for hydrothermal synthesis of mixed nanostructured zirconia doped with different REO/ZrO2 molar ratios by a cost efficient process will be developed. The mixed REO-ZrO2 materials obtained will be used as target material to obtain TBCs at TRL 4 and validated on industrial systems by RF sputtering and electron beam deposition and study their structural stability vs. mixed REO/ZrO2 molar ratios for TBCs aiming to increase the lifetime of Ni/Cr alloys or reduce the CRMs content in substrate alloys. Bulk mixed REO-ZrO2 will be obtained at ICMCB-CNRS, Bordeaux by using various innovative sintering techniques(TRL 4-6). Densification process and ionic conductivity will be optimized for SOFCs. Elimination of separation stages and

mixed REO utilization instead of individual REO, if validated in applications, may reduce production costs along the whole fabrication cycle from raw materials to product, providing nanomaterials for high-tech applications in high temperature coatings (up to 1400-15000C) and SOFCs with operating temperature around 4000C, with cost efficiency and sustainable production.

Project website: http://tandem.inoe.ro/mgm.html

Abstract:

The specific innovation objectives of the TANDEM project are related to the development of a new generation of well-adherent and hard diamond-like carbon coatings (DLC) with good temperature stability. The novelty is in coatings combining high hardness (>40 GPa), smooth surface and low internal stress, allowing the deposition of adherent thick coatings (min. 3 μm) on metal parts with complex geometries. These combined features are especially desirable for automotive industry, in which DLC represent the largest proportion of thin film coating solutions. The benefits generated by the new DLC coatings will be: significantly improved fuel economy (protection of natural resources), reduced emissions (protection of the environment) and improved durability (lower waste and maintenance). TANDEM consortium addresses the whole chain from the synthesis of a coating to the final applications.

Abstract:

Thin film based PV structures are well fitted for space technology, due to their reduced mass. This proposal aims at investigating technological routes for fabricating thin film based multiple junction photovoltaic (PV) structures of the type ZnS/ZnSe/CdTe in superstrate configurations and to study their endurance to energetic (2-10 MeV) protons and alpha particles, which are the main components of cosmic rays, at 10^10 - 10^14 cm^-2 fluencies. In the superstrate configuration one starts with depositing the transparent front-electrode onto the glass substrate which supports the entire structure, and then, on top of it the ZnS, ZnSe, CdTe layers and finally the back-electrode. The efficiencies of the cells in superstrate configurations will be characterized, and also their endurance to irradiation. Special attention will be paid to the physical properties and the electrical response of the back-contact metal/CdTe. CdTe, an excellent photon absorber with a forbidden gap of 1.4 eV and a large light absorption coefficient, is known as a “difficult” semiconductor: due to its rather large work function, a special care must be taken to prepare a quasi-ohmic low-resistance contact with a metal. Ion implantation will be used to control electrical properties of CdTe layer, by doping with properly selected electrically active impurities. A special attention will be paid to the quality of interfaces; an optimization of the PV structures will be performed. The nature of the defects introduced by irradiation will be studied and their influence on the performance of the structures will be indicated.

Abstract:

The project aims to develop novel products and knowledge in antimicrobial nanostructured coatings for medical applications like critical surgical instruments (scalpels, knives, forceps and scissors) to reduce superficial and deep surgical site infections and to improve quality of life. Nanostructured materials of MeNPs/MeONPs type (MeNPs = Ag, Cu, MeONPs = CaO, MgO, ZnO, TiO2) with average MeNPs size of 10-20 nm and average MeONPs size of 30-50 nm) and high antimicrobial activity will be obtained by an innovative chemical synthesis of colloidal suspensions containing ecological NPs with 0.1-0.5 wt.% MeNPs and 1-3 wt.% MeONPs. Chemical deposition of MeNPs on MeONPs supports will be realized by a self-assembled nanolayers coating process, being a new and efficient approach in control of NPs size and stability. A higher content of MeNPs will be obtained in comparison with the existent solutions. The MeNPs and MeONPs mixtures will show synergistic effects of antimicrobial properties compared with those of MeNPs and MeONPs used alone. Ecological and efficient processing methods will be used to obtain and deposit the bioactive agents designed to inhibit the adhesion of microorganisms on stainless steel supports that show lack of antibacterial properties. The MeNPs/MeONPs composite powders will be deposited by different methods such as Thermal Evaporation, EBPVD (e-gun), Sputtering Deposition (Magnetron) and Arc-PVD (Plasmotron) on the metallic substrates with ensuring a good adhesion without changing the substrates original properties. Nanostructured coatings with homogenous and dense surface without any faults (pinholes and cracks) will be achieved at low temperatures to not affect the materials properties. Optimized coatings will be developed by a graded structure and adjusting stress level. Other original and innovative aspect is related by sputtering targets development from selected nanostructured materials by spark plasma sintering (SPS) process, where nanostructure features are maintained since grain growth and the development of equilibrium states are suppressed. The project addresses to the priority thematic of the PARTNERSHIPS PN-II-PT-PCCA-2013-4 program, Domain 7. “Materials, processes and innovative products“, Research field 7.1 Advanced materials, Thematic Area 7.1.6. “Advanced materials and biomaterials for health quality increasing“ with a direct impact in Domain 4. “Health” and European Research Area (ERA)-Nanomaterials. The project has inter-disciplinary, multi-disciplinary and trans-disciplinary nature being carried out by high skilled specialists with complementary expertise. Certified prototypes and end-products of critical stainless steel surgical instruments coated with antimicrobial MeNPs/MeONPs nanostructured materials with uniform and homogeneous mono/multilayer with thickness ranging 0.1-50 µm will be obtained. The coatings will have high resistance to mechanical wear, high resistance to heat stresses, high hardness, low friction coefficient and good adhesion to substrate. The novel products will be introduced on the market only after their certification granted by the Health Ministry from Romania. The coated products will be at a competitive cost with uncoated ones, contributing to the requests of the global and national socio-economic environment in the field of advanced materials and health with a major impact in reducing surgical site infections. Knowledge protection will be made by two patent applications registered to the national State Office for Inventions and Trademarks (OSIM). Results dissemination will be made on a large scale by publishing scientific papers in ISI ranked journals, attendance at national and international events, setting up and updating project web site, elaboration of dissemination materials.
