In line with the Key Strategic Orientation (KSC) C of the Strategic Plan “Making Europe the first digitally led circular, climate-neutral and sustainable economy through the transformation of its mobility, energy, construction and production systems” and with the Circular Economy Action Plan “For a cleaner and more competitive Europe”, the proposal “TURBISURF” intends to produce new and repaired complex surfaces of hot section turbine components using digitised, environmentally friendly, energy and chemical-lean processes. Self-monitored electrochemical processes will allow to selectively strip oxide and corrosion products and worn coatings without affecting the expensive substrates. The digitisation will target local areas or the full complex external and internal surfaces. Each component will be processed individually within the same batch allowing full customisation of the process. The same principle will be applied to electropolish the local or the whole surfaces dimensionally restored by additive manufacturing allowing to tailor the roughness of the surfaces. After cleaning and restoring or directly applied onto new components, slurry coatings with and without Ni and/or Pt electroless sublayers will be deposited on digitised surfaces with 3D computed movement/rotation. Destructive and Non Destructive Testing (NDT) will allow to estimate the lifetime of the new coated and repaired complex surfaces vs. the state of the art. The shared results onto different components will contribute to standardise the digitised processes developed in TURBISURF. The Lifecycle analysis (LCA) will assess the economic and ecologic contribution of the approaches to circular economy with a view of real exploitation in European SMEs and large companies. The Academic and Industrial consortium will develop the skills of young European scientists, engineers and economists on the advanced digitalised processes developed here. Overall, a digital transformation of the processes will ensure that the Destination “Climate neutral, circular and digitised production” is successfully reached after 4 years of involvement and that other business sectors (e.g. automotive) can benefit from TURBISURF.
