Abstract:

THE PROBLEM OF OXIDATION IN THE HOT SECTIONS OF A MODERN JET ENGINE IS SERIOUS. IT IS SAID THAT A JET ENGINE WITH UNPROTECTED TURBINE BLADES CANNOT MAKE A SINGLE TRANSATLANTIC FLIGHT BECAUSE OF OXIDATION. NICKEL-BASE SUPERALLOYS THAT ARE USED IN THE HOT SECTIONS ARE PROTECTED BY OXIDATION RESISTANT SURFACE COATINGS. THE COATING TECHNOLOGY FOLLOWS THE DEVELOPMENT IN NICKEL-BASE SUPERALLOYS. THERE IS A RISING ECONOMIC PRESSURE TO ENHANCE THE OXIDATION RESISTANCE OF BARE ALLOYS AND THE COATING PERFORMANCE. THIS PRESSURE IS DUE TO THE HIGH COST OF MANUFACTURING AND REPLACEMENT OF HOT SECTION COMPONENTS. INNOVATIVE METHODS ARE THEREFORE REQUIRED TO MITIGATE THE OXIDATION PROBLEMS. MODIFICATION OF SURFACE CHEMISTRY BY ION BEAMS IS CONSIDERED AS A POTENTIAL METHOD TO ENHANCE THE OXIDATION RESISTANCE OF BARE ALLOYS AND/OR THE COATING PERFORMANCE. THE TECHNICAL FEASIBILITY OF THIS APPROACH IS CONSIDERED IN PHASE I IN RELATION TO THE NICKEL-BASE SUPERALLOY SINGLE CRYSTALS THAT ARE SELECTED FOR APPLICATION IN THE 1980S JET ENGINES. COMBINATIONS OF SURFACE CHEMISTRY MODIFICATION AND COATING WILL BE CONSIDERED. ISOTHERMAL AND CYCLIC OXIDATION TESTS ARE PLANNED TO ALONG WITH THE SURFACE MICROSTRUCTURAL CHARACTERIZATION BE ADVANCED TECHNIQUES TO ESTABLISH THE EFFICIENCY OF THE PROCESS.
