Solvo-thermal treatment was used to chemically densify thermalsprayed oxide based coatings. This allows to reduce significantlyits porosity whilst it improves the cohesion and hardness. As aconsequence, this leads to a better thermal shock and wearresistance. This innovative process has been successfully used toimprove the corrosion resistance against liquid aluminum alloyswhere coatings face combined chemical, thermal and mechanicalloads.
