Notes:
Thermomechanical and electrical properties of zirconia-based ceramics have led toa wide range of advanced and engineering ceramic applications like solid electrolyte inoxygen sensors, fuel cells and furnace elements and its low thermal conductivity has allowedits use for thermal barrier coatings for aerospace engine components. A comparisonbetween CoNiCrAlY bond coat and zirconia plasma sprayed coatings on creep tests of theTi-6Al-4V alloy was studied. The material used was commercial Ti-6Al-4V alloy. Yttria (8wt.%) stabilized zirconia (YSZ) with a CoNiCrAlY bond coat was atmospherically plasmasprayed on Ti-6Al-4V substrates by Sulzer Metco Type 9 MB. Constant load creep tests wereconducted on a standard creep machine in air on coated samples, at stress levels of 520MPa at 500ºC to evaluate the oxidation protection on creep of the Ti-6Al-4V alloy. Resultsindicate that the creep resistance of the ceramic coating was greater than metallic coating
