  • METHOD FOR FABRICATING A THERMAL BARRIER COVERING A SUPERALLOY METAL SUBSTRATE, AND A THERMOMECHANICAL PART RESULTING FROM THIS FABRICATION METHOD
    Publication number: 20120028056
    Abstract: A fabrication method of fabricating a thermal barrier covering a superalloy metal substrate, the thermal barrier including at least an underlayer and a ceramic layer, the method including: smoothing a surface state of the underlayer by at least one physicochemical and/or mechanical process prior to depositing the ceramic layer such that a number of defects presenting a peak-to-peak difference lower than or equal to 2 ?m is at most five over any distance of 50 ?m, and then depositing the ceramic layer. The method can be applied to turbine blades.
