Multilayer coatings as functional materials
A Ukrainian university offers the technology of multilayer functional coatings deposition by electrochemical method. A great attention is paid for ecological aspect of coating deposition and the possibility of using them in green technologies. The technology of copper-nickel coatings is at Technology Readiness Level (TRL) 4. The technology of other coatings is at TRL 3. The University seeks industrial partners and academia and is open for research and technical cooperation agreements.
Type of Partner: R&D Institutions that have the opportunity to conduct technology testing; certified laboratories of industrial enterprises having galvanic lines. Role of Partner: Ideal partner is expected to test the properties of the coating under research cooperation agreement; partner is expected to adopt the technology for their needs under technical cooperation agreement.
The university has experience in working with functional materials. The staff has experience (including international) in electrochemical formation of functional coatings. The group of researchers has equipment for electrochemical studies and instrument for testing microhardness. The multilayer coatings consist of many thin (less then 100 nm thickness) layers of metals, alloys or hydroxides of different composition. The number of alternate thin layers in coating can be around 300. The copper-nickel multilayer coatings are designed for increasing the corrosion resistance and improving the mechanical properties of the surface of metal products, as well as providing the catalytic properties of the anode surface in reactions of organic substances oxidation, such as methanol in fuel cells. The copper-nickel multilayer coating containing 50-80% of nickel is characterized by microhardness of 410-680 HV, plasticity. It is well-adhered with an electronegative surface such as the surface of neodymium magnets. Multilayer coating consisting of layers of nickel-copper alloy and mixture of metals and their hydroxides is characterized by improved properties, compared with single-layer coating. The catalytic activity in the electrooxidation reactions is increased in 1.5-2 times. The stability of surface properties is also higher. Zinc-nickel coatings show high corrosion resistance as they containing mainly γ-phase. Varying the composition of alloy in multilayer coating leads to the formation of the coating with desired protective properties. The multilayer antimony-doped tin dioxide coating on titanium substrate obtained by electrochemical method provide catalytic activity in electrochemical destruction of organic pollutions (e.g. phenol). The coating has higher life service compared to antimony-doped tin dioxide coating. The economic appropriateness of using multilayer coatings caused by saving materials due to product life increase and the production cost reduction. The University is looking for industrial partners and R&D Institutions to jointly develop and commercialize the technology and is open for research and technical cooperation agreements.
Advantages and innovations
Main advantages: - high microhardness and simultaneously plasticity of the copper-nickel multilayer coating, - catalytic activity of copper nickel hydroxide multilayer coating in electrooxidation reactions is increased by 1.5-2 times compared to single-layer coating that leads to increase in productivity of electrolysis - stability of copper nickel hydroxide multilayer coating surface properties is 1.3-1.6 times higher compared to single-layer coating (accelerated laboratory tests). - increased corrosion resistance and microhardness of the multilayer coating as compared to single-layer alloys based on zinc and nickel - multilayer antimony-doped tin dioxide coating on titanium substrate have higher life service compared to antimony-doped tin dioxide coating.

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
