Objective
DEVELOP OF ZIRCONIA-BASED THERMAL BARRIER COATINGS USING THE CHEMICAL VAPOUR DEPOSITION TECHNIQUES FOR APPLICATION TO GAS TURBINES.
THERMAL BARRIER COATINGS ARE REQUIRED ON MANY PARTS OF ADVANCED GAS TURBINE ENGINES. ZIRCONIA IS THE BEST AVAILABLE MATERIAL BECAUSE OF ITS UNUSUALLY LOW THERMAL CONDUCTIVITY. PRESENT TECHNIQUES PRODUCE ROUGH, SOMEWHAT POROUS COATINGS OF UNEVEN THICKNESS. THE PROPOSED CVD TECHNIQUE SHOULD MAKE POSSIBLE THICK COATINGS WITH THE ADVANTAGES OF UNIFORM THICKNESS, SMOOTH TEXTURE AND LOW POROSITY. AN ADDED BENEFIT SHOULD BE IN THE IMPROVED THERMAL SHOCK RESISTANCE THAT IS EXPECTED FOR SUCH COATINGS DUE TO THE COLUMNAR GRAIN STRUCTURES TYPICAL OF CVD LAYERS.
TWO METHODS WILL BE STUDIED FOR THE CHEMICAL VAPOUR DEPOSITION OF ZIRCONIA:
1) HYDROLYSIS OF ZRCL4 USING TRACE AMOUNTS OF WATER VAPOUR GENERATED FROM MIXTURES OF CO2/H2 AT TEMPERATURES IN THE RANGE 700-1000C.;
2) PYROLYSIS OF TETRA-ALKOXY ZIRCONIUM (ZR(OR)4) AT TEMPERATURES IN THE RANGE 400-1000C.
TWO DIFFERENT TYPES OF CVD REACTOR WILL BE USED IN THIS STUDY Y AND THE PHASE STABILIZATION EFFECTS OF ADDINNG SMALL AMOUNTS OF YTTRIA AND OTHER ADDITIVES WILL BE INVESTIGATED. THE EFFECTS OF DEPOSITION AND GENERATOR TEMPERATURE, PRESSURE AND FLOWRATES, AS WELL AS ADHESION AND COHESION OF THE COATINGS ON NICKEL ALLOY SUBSTRATES, WILL ALL BE EXAMINED TO OPTIMIZE THE QUALITY OF THE COATINGS. TRIAL GAS TURBINE COMPONENTS OF CLOMPLEX SHAPE WILL BE SUPPLIED TO GAS TURBINE MANUFACTURERS FOR THEIR EVALUATION.
