	Performance and Thermal Stability of Pt-modified Al-diffusion Coatings for Superalloys under Cyclic and Isothermal Conditions 2005 Auteurs : A.D Kennedy, A. Littner, P. Moretto, F. Pedraza, L. Peich, M. Schütze et T. Weber Masquer le résumé In this pa 1150°C of Pt-aluminide coatings deposited on a single crystal Ni-based superalloy is reported. The different coatings involve the well-known bi-phase (Ni,Pt)Al and PtAl2 as well as single phase (Ni,Pt)Al coatings with various compositions and microstructures. The results showed that the cyclic oxidation performance depends strongly on the average Pt-content present in the coating and, to a lesser extent, on the coating microstructure. Moreover, no relevant effect of the Al content could be evidenced. Surface deformation occurred during exposure and was attributed to phase transformations within the coating. This assumption was confirmed by isothermal experiments between 1050 and 1200°C. Post-experimental investigations of tested specimens were performed by optical and scanning electron microscopy, X-ray diffraction and EPMA.

Keywords : oxidation protection Source : HAL   Darmstadt Rotor No. 2, II: Design of Leaning Rotor Blades 2003 Auteurs : Jörg Bergner et Martin Hoeger Masquer le résumé For Darmstadt University of Technology's axial singlestage transonic compressor rig, a new three-dimensional aft-swept rotor was designed and manufactured at MTU Aero Engines in Munich, Germany. The application of carbon fiber–reinforced plastic made it possible to overcome structural constraints and therefore to further increase the amount of lean and sweep of the blade. The aim of the design was to improve the mechanical stability at operation that is close to stall. To avoid the hazard of rubbing at the blade tip, which is found especially at off-design operating conditions close to the stability limit of the compression system, aft-sweep was introduced together with excessive backward lean. This article reports an investigation of the impact of various amounts of lean on the aerodynamic behavior of the compressor stage on the basis of steady-state Navier-Stokes simulations. The results indicate that high backward lean promotes an undesirable redistribution of mass flow and gives rise to a basic change in the shock pattern, whereas a forward-leaning geometry results in the development of a highly back-swept shock front. However, the disadvantage is a decrease in shock strength and efficiency.

Casting process The process, based on natural cooling, proved to be suitable for standard furnaces, in particular for DS-structures (multiple grains) and components up to 200 mm long. Engine tests will be performed. NDT method Turbomeca's work resulted in significant progress in understanding the interactions of e.g. spurious grains and X-rays wall thickness effects covered by their CRISTAL AND REFOCALISATION-system. Automatisation is still an objective to be dealt with. Hide general information The availability of affordable and reliable single crystal components for high temperature applications, in particular in gas turbines, is an essential aspect for competitive engines. New approaches are necessary to reduce the costs of these components, which are still to high for certain applications. This project consists of three complementary objectives which combined will significantly decrease costs of single crystal components with high performance potential. The first objective is to improve the performance of the single crystal material by careful balancing of conventional Ni-base alloy chemistry (rather than following the conventional method of adding extremely expensive elements like Re). The second objective is to significantly lower production costs by utilizing conventional vacuum casting furnaces available even in smaller investment foundries and by reducing cycle times. Process parameters will be controlled by mould design rather than by heating/cooling devices. The third objective is to lower quality assurance costs for detecting orientation and grain structure defects by simultaneously increasing the reliability of quality control test results.
