Abstract:

The goal of the HEASYNTCORR project is the development of a new

technology for the electrochemical synthesis of high-entropy alloys

(HEAs) coatings with superior corrosion resistance and mechanical

characteristics, for applications in marine environments. The HEA thin

films will be electrodeposited on copper and steel, for the protection of

ship propellers and propeller shafts against galvanic corrosion,

cavitation erosion and wear. By the project implementation, the

electroplated parts obtained will present an extended lifetime, at

lower fabrication costs than the current repair technologies. The

project will start from the technology readiness level 2 (TRL2) and end

with the demonstration model of the new technology validated at

laboratory level (TRL4). The HEA coatings will be obtained by

electrochemical codeposition of the component elements in

non-aqueous electrolytes, using various complexing agents. The

obtained thin films will be physical, structural, tribological and

mechanical characterized. The corrosion tests will be done in the

operational environment (sea water). The thin films properties will be

improved by heat treatment process. The main project objectives are:

1. Electrochemical studies. Selection of HEA compositions and

electrolyte systems. 2. Establishing of the technological parameters

for the synthesis of HEA thin films. 3. HEA thin films complex

characterization. 4. Technology validation.5. Patent application.

Dissemination. The novelty of the project consist in: a. HEA thin films

obtaining by electrodeposition b. fundamental electrochemical studies

of the electrolytes-HEA systems; c. systematic study of the process

Abstract:

The major objective of the project is the development of an innovative technology and of a new installation, for the ecological processing of WEEEs in microwave field. The method is applied for the first time in Romania, and the implementation in the economy will have a considerable impact on reducing the environment pollution, increasing the degree of WEEE contained nonferrous metals recovery and their reintroduction in the economic cycle. The project theme integrates in PCCA 2013 domain 3 themes 3.2.3 Technologies for disassembling complex products and revaluing component subassemblies. The project addresses the key issue in the field of environment protection: reducing pollution and activities harmful for human health by decreasing the WEEE quantity, developing innovative technologies for reintroduction in the economic cycle of important sources of nonferrous metals and diminishing CO2 emissions. The project responds to PCCA 2013 objectives by: ►consortium constitution (one prestigious university, 2 national research institutes and 2 economic agents, one specialized in microwave applications) and joint performing of research activities →objective Stimulation of research-development activity performed in partnership ►developing advanced technologies in environment ecologization by innovative processes for WEEE processing in microwave field →objective Connecting applicative research to the requirements of the economic environment by developing advanced products and technologies ►the significant co-financing of the research expenditures and active SME involvement → objective Growth stimulation of private sector expenditures in research-development ► the acquisition of efficient equipment and the integration of young PhD students in the work groups contributes to the objective Developing the infrastructure and the competencies of the human resources. The major scientific and technological objectives of the project are: i. developing the process of WEEE melting and treatment of resulting gases in microwave field ii. hydrometallurgical and electrochemical separation of the metals in the multicomponent alloy resulting from melting by: soluble anode electrolysis, acid and alkaline solutions electrodeposition, ionic liquid extraction iii. improvement of WEEE processing in microwave field iv. innovative technology for ecological WEEE processing v. demonstration and validation of the new installation. The novelty and originality of the project consist in: a. WEEE melting in microwave field and complete separation of the metallic fraction b. treatment system for gases resulting from WEEE melting by thermal oxidation in microwave field of harmful compounds and transformation in nonpolluting compounds, not applied in Romania c. complete selective separation of metals in the multicomponent alloy resulting from melting, by modern methods: chemical, electrochemical and ionic liquids. The main project results are: ●innovative and ecological technology for WEEE processing in microwave field ●innovative installation for ecological WEEE processing (including gas treatment system in microwave field) ●patent applications ●dissemination by ISI indexed articles, conferences, workshops, seminaries. Project impact/potential benefits: ►strengthening the cooperation between research organizations and economic agents ► research infrastructure development and increasing the institutional capacity of the partners for participation in national and international RD projects► increasing SME competitivity by developing advanced technologies for ecological WEEE processing and increasing the turnover by 5-10%► patent exploitation► social impact by increasing life and environment quality, creation of 3 jobs► environment impact: ecological technologies for WEEE processing, recycling contained metals, decreasing energy consumption by 30%.
