Abstract

The oxidation behaviour of a thermal barrier coating TBC system is a major concern as the growth of the thermally grown oxide TGO layer on the bondcoating creates stresses that greatly favour the thermal barrier spallation To delay the loss of the thermal protection provided research has focused on the bondcoating composition and microstructure as well as on the parameters required for a suitable preoxidation treatment before the deposition of the ceramic top coat Platinum is known to enhance the oxidation/corrosion resistance of MCrAlY coatings The effect of Pt on the oxidation behaviour of a NiCoCrAlYTa coating was assessed in this study In addition preoxidation treatments were conducted to determine if the oxidation behaviour of the modified NiCoCrAlYTa coating could be further improvedTurbomeca Safran Group are gratefully acknowledged for providing the samples and for the financial support of this study Authors express their thanks to Praxair ST which manufactured the bondcoatings to Snecma for grit blasting the TBC systems and to CCC which made EBPVD thermal barrier coatings JP Grenet from IPREM Pau France is gratefully acknowledged for Raman and photoluminescence spectroscopy analyses Turboméca and CNRS for the doctoral grant of A Vande Put
