Develop specialised corrosion and erosion-resistant coatings for geothermal energy utilisation

The Geo-coat project develops specialised corrosion- and erosion- resistant coatings, based on selected High Entropy Alloys (HEAs) and Ceramic/Metal mixtures (Cermets), to be applied through thermal powder coating techniques (primarily high velocity forms of HVOF / Laser cladding) specially developed to provide the required bond strength, hardness and density for the challenging geothermal applications. It aims to design the new high performance coatings to resist each of the specified threats or combinations of threat, as experimentally derived at key failure points within geothermal runs, and to apply them only to the affected components.

Impact and objectives

  • Maintaining and improving the competitiveness and sustainability of the European geothermal industry via a lifecycle approach to material and system specification, allowing them to meet requirements for resistance to corrosion and erosion problems and to reduce the overall through life costs.
  • Improving design capability at the early stages to allow cost and performance optimisation of materials, virtual testing of designs, transparent and collabortaive communication with clients, and overall reduced sunk costs in design and capex.
  • Increasing production efficiency, longevity, reduced downtime through failures/and or treatments, reduced energy consumption, enviornmental impacts and production costs.
