Development of technologies for advanced treatment of metal alloy surfaces for special applications in the aerospace and bio-medical sectors

Final Activity Report Summary - SURFACES (Development of Technologies for Advanced Treatment of Metal Alloy Surfaces with applications in the Gas Turbine sector)

This Marie Curie IAP project aimed to implement significant R&D work and transfer of knowledge between one industrial partner and two Universities in relation to protective coatings for Nickel alloy turbine blades used in aero-engines. The overall project consisted of two sub-projects: Sub-project 1: The successful deposition of high quality Thermal Barrier Coatings onto Nickel alloy substrates using Chemical Vapour Deposition(CVD) technology. If successful this would permit the coating of 3-dimensional components without sample manipulation during the coating process - which would be a significant advance on the current state of the art.

Sub-project 1 was carried out between Partner 1 (SRTAS) and Partner 2 (Cranfield University). Although some excellent research and knowledge transfer was carried out, with hindsight it can be said that this project was so extremely challenging that resources on a much greater scale than was possible in this project would have been necessary for any hopes of a successful outcome.

The project was terminated after about 12 months when it was clear that the goals were not achievable within the context of the available time and resources. Sub-project 2: This project was carried out between partner 1 (SRTAS) and partner 3 (University of La Rochelle). The aim was to develop better solution-based methods for the removal of old protective coatings on Nickel alloy turbine components.

More specifically the aim was to surpass the present state of the art by developing solution based methods for "stripping" old coatings that were more selective, more reliable, and more environmentally friendly than the current state of the art. A high degree of success was achieved with this sub-project, and the outputs of this sub-project constitute the principal technical achievement and the principal transfer of knowledge of the project as a whole.
