Abstract:
The scientific research project entitled "Composite material with new ceramic layer processed by laser techniques for corrosion and high temperature applications - LASCERHEA" is proposed by an interdisciplinary / complementary team from Romania: CO-Polytechnic University of Bucharest, Partner P1 - INFLPR and Partner P2-UPS Pilot, with highly experienced personnel and modern laboratories for obtaining and characterizing metallic materials (CO), unique laser processing facilities and equipment for microstructural characterization (P1) and experience in computer modeling and simulation (P2). The project is addressed to the field of Eco-Nano Technologies and Advanced Materials, for obtaining new ceramic composite materials processed by laser techniques for 5G industry. The main objective of the project is to offer on the industrial market new functional composite materials based on ceramic layers, to be used in high temperature and corrosion conditions. The metal substrate will be the AlCrFeMnMoNiTaW alloy, which will contain at least 5 different chemical elements, with equimolar atomic participation. For the generation, structuring, and homogenization of the ceramic layer, methods of laser coating and laser thermal treatments will be applied, using powder type additive material (alpha alumina and tungsten carbide) and chemical active solutions. The samples will be subjected to laboratory investigations (microstructure, micro-hardness, adhesion, resistance to corrosion, tension and bending, conductivity and thermal expansion). The alumina layer will also be deposited by the Pulsed Laser Deposition technique on different substrates, as a reference sample for high structural and morphological properties. The proposed method allows obtaining thin films of Al2O3 with different functional properties. To optimize the laser processing parameters, a simulation program will be developed to reduce the number of experiments.

Abstract:
The "Corrosion resistant X10 NiCrAlTi 32 20 refractory alloy" project, proposed by an inter-disciplinary team composed of Coordinator IMA SC METAV (SMEs) and P1 - UPB (CD), aims to achieve a new steel brand of refractory austenitic alloys grade, X10NiCrAlTi 32-20, with high corrosion resistance and high temperatures resistance, similar with high alloyed nickel alloys (INCOLOY 800).
The new alloy is intended for semi-products, components or spare parts execution with high resistance at high temperatures and corrosion in areas such as chemical, gas and petrochemical, aeronautics, food and pharmaceutical industries.
The development of the elaboration-casting technology for this high alloyed alloy with 32% Cr and 20% Ni stabilised with titanium, will bring economic benefits and prestige for the applicant (IMA METAV), one of the few special alloy casting parts producer in Romania, with a necessary production infrastructure (VIM + VAR).
Since the alloy machining main problem is the microstructural stability loss by hot-cracking, the project foresees original elements for the microstructural consolidation, respectively Ti, Al and lanthanides (Ce) microalloying for granulation finishing and chromium carbides precipitation constraint, which determine the alloy brittleness at elevated temperatures.To avoid additional hardening and to keep the metal matrix stiffness, the cumulated microalloying elements will be up to 0.8% (Al+Ti+Ce).
The ownership right distribution on the results will be established and agree between partners in the collaboration agreement, at the project start-up. The obtained scientific and technical results through the project deployment will be disseminated on a large scale by participating at scientific and technical manifestations, publications and web page.

Abstract:
The scientific research project ADVANCED METALLIC MATERIALS FOR 4R NEW GENERATION NUCLEAR POWER PLANT – NUCLEARMAT is proposed by a complementary and interdisciplinary scientific consortium consisting in specialists from UNIVERSITY POLITEHNICA of BUCHAREST, S.C. OPTOLELECTRONICA 2001 SRL, IFIN – HH, SC UPS PILOT ARM SRL and SC METAV – CD Bucharest. The project proposes the obtainment of a wide range of FeCrAl class alloys with corrosion and erosion resistance in oxidizing liquid metal environment, at high-temperature and high field penetrating and ionizing gamma radiation. These metallic materials have to be suitable for use in 4R generation nuclear reactors cooled with liquid metals (lead, or mixtures of liquid metal, lead-bismuth). Metallic alloys for 4R generation nuclear power plants must meet the following basic requirements: to be resistant to oxidation at high temperatures; to provide corrosion resistance and erosion in liquid metal environments; to be able to form a self-generated continuous protective oxide layer, with high adhesion, on alloy surface.
Research consortium proposes a wide class of FeCrAl alloys micro-alloyed with yttrium and/or zirconium and/or titanium, which will be obtained in a vacuum arc remelting (VAR) installation or in a vacuum induction furnace (VIF). The chemical composition of alloys will be:
Al = 4-10%, Cr = 12-18%, (Y, Zr, Ti) = 1-3% and Fe - balance. To homogenize and refine the oxide layer formed on the surface of metal alloys shall be designed and applied laser surface treatments. To test these FeCrAl alloys will be designed and produced an original experimental stand (experimental model), allowing temperature variation between 400 ... 600 OC. The obtained samples will be immersed in liquid metal environments and intense gamma radiation field (high energy gamma rays (mean energy 1.125 MeV) radiated by Co-60 sealed radioactive sources) at CNCAN authorized laboratories for work with radioactive sources. FeCrAl alloys samples will be irradiated under high temperature both immersed in liquid metal (molten lead) and in air to study the effect of high doses of gamma radiation on the microstructure of the samples. Before and after testing, samples will be subject to laboratory investigations to analyze the behavior of the oxide layer after operation in such environments.
The main objectives and outcomes of the project are:
• Obtaining, testing and laser surface treatment of new alloys for 4R generation nuclear power plants;
• Preparation of technical specifications for new nuclear plants dedicated materials (limits on the use of new materials, application areas, mechanical properties, physical and chemical properties of materials) in order to patent the original solutions;
• Establishing the opportunities to participate in international projects based on the experience gained through the project;
• Mathematical modeling of laser-metal energy transfer and simulation of laser irradiation;
• Development of new technologies for laser irradiation with auto-generation of layers;
• Design and implementation of an experimental model (experimental stand) for tests in liquid metal corrosive and erosive environments at high temperatures;
• Behavior testing (changes of surface structural properties) of FeCrAl alloys in liquid metal environments and in the presence of intense gamma radiation field (generated by radioactive sources of high activity Co-60);
• Protection of Intellectual Property Rights project results (patents);
• Widespread dissemination of scientific research results developed within the project (articles, conferences, round tables etc.).

Abstract:
The project develops a 3-D mechatronic system for human locomotion rehabilitation and will be used for patients with disabilities due to neuro-motor impairments, promoting the usage of a world-wide premiere 3-D mechatronic system. Actual systems are developed on 2-D platforms.
RELIVE project is marketable due to the use of commercially available equipment.
The project aims to achieve, in partnership, a controlled habitat (CH), similar to the indoor and outdoor environment. Its purpose consists in the recovery of neuro-motor functions for patients with neurological conditions, in similar conditions as the environmental 3-D ones. Recovery is based on the patient’s active motion (walking and other activities) on three directions: straight, curve, stairs, ramps, with direction and sense change.
The controlled habitat (CH) consists in a mechatronic complex system (MCS) that monitors and commands patient’s movement. MCS operates in a treatment space endowed with several simulation sub-systems. Inside CH there are various real objects and devices, to ensure a comprehensive simulation of real, expected or unexpected conditions. This therapeutically approach presents the advantages: precision in evaluating patient’s functional parameters, ability to develop a sustained long term activity, stimulation of attentiveness and impulse for functional recovery of impaired people, through controlled habitat stimulus and permanent evolution feedback, accumulation of information for medical rehabilitation research, option for long distance monitoring, kinetic exercises impossible to be performed with a therapist.
The innovative technological solutions combine systems of sensorial motion data acquisition, mechatronic and mechanical flexible devices with virtual reality. Achieving an audio-visual, somato-sensory and neuro-propioceptive feedback, we aim to obtain neurological injured patient’s functional improvement, socio-familial and professional reinsertion and life quality increase.
