Steels, copper and aluminium alloys are the most important metallic materials widely used in marine engineering due to their good resistance to corrosion as well as their many other excellent properties. One promising approach for improving their corrosion resistance in seawater it would be to develop a controllable physical barrier to corrosion in the form of films and coatings. Many different approaches, including coating with polymers, organic layers and other metals and alloys, have been developed. High entropy alloys (HEAs), being composed of five or more principal elements in different ratios, are potentially suitable for many applications due to their simple crystal structures and extraordinary properties such as high strength, corrosion and wear resistance. The goal of the demonstration experimental project (PED) 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 coatings will be obtained by the electrochemical co-deposition of the component elements in non-aqueous electrolytes, using various complexing agents [4]. 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 processes.
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.
