Final Activity Report Summary - SMART COATINGS (Design and Development of Smart Coatings for Aerospace Applications)
1. establish the mechanism of degradation of Ni-base super alloys, which are used to manufacture aerospace turbine blades, due to oxidation, hot corrosion and oxidation and sulphidation, for operating temperatures up to 1 250 degrees Celsius;
2. design and produce compositionally optimised smart coatings to protect super alloys from such modes of degradations;
3. design and produce smart coatings to protect titanium alloys, such as IMI 834, used in compressor section components, against degradation by oxygen absorption, oxidation, alpha case formation and hot corrosion, corresponding to temperatures of up to 500 degrees Celsius;
4. study the degradation behaviour of the designed smart coatings deposited on super alloy and titanium base alloys, establish the modes of degradation and assess the effectiveness of the produced coatings.
All these objectives were achieved.
