Following its kick-off in February 2018, the Geo-Coat project now enters its final phase where testing of Geo-Coat coatings in real geothermal environments are being concluded. The project has made significant progress with some promising results, novel coatings that are aggressive environments specialised corrosion- , scaling-and erosion-resistant coatings and bulk materials, based on selected high-entropy alloys, ceramic/metal mixtures, nickel-phosphorous-polytetrafluoroethylene and metal matrix composites.

‘Geothermal power production’ webinar
Our amazing speaker, Sigrun Nanna Karlsdottir, Professor at University of Iceland - Háskóli Íslands, received lots of positive feedback for her excellent presentation, which covered the fundamentals of geothermal energy production and the associated challenges including material issues and corrosion. The presentation also investigated how the coatings being tested by the GeoCoat Project are aiming to mitigate these problems. Click here
Geo-coat gets preliminary results from exposure tests!
The resistance of the coatings and MMCs to the harsh testing environments is currently being analysed by means of Optical microscopy, SEM-EDX and other in-depth characterisation techniques. The aim is to assess the ability of the coatings to resist erosive load from the geothermal fluid flow, permeation of geothermal fluid and formation of localised forms of corrosion, which could be detrimental to the lifetime of the coated components.

Testing updates from Innovation Center Iceland
The SEM microstructural samples, weight loss measurement samples and U-bend samples were analysed at Innovation Center Iceland (ICI). The findings so far are quite interesting. Many coatings show promising results and interesting corrosion phenomena have been identified. Some Geo-Coat coatings seem unaffected by the geothermal conditions as compared to the carbon steel, which exhibited significant corrosion after 3 months in the wellhead. Click here
Erosion-corrosion testing @ weir
Weir Group’s dedicated erosion-corrosion laboratory testing facility has aided in understanding of the corrosive wear resistance of the Geo-Coat materials and has helped to identify the most attractive coatings for geothermal applications. Click here
Electro spark deposition at Bucharest
"Our experience in the mechanical alloying field, represented an important advantage in this project. The materials produced by this method exhibit a high alloying and homogenization degree, but also no oxidation or contamination issues due glovebox manipulation", says Laura Geambazu, as she talks about the coatings works at University "Politehnica" Bucharest.
