Abstract

Abstract

The bonding strength of the thermal barrier coating including ASP and EB-PVD is studied under different high temperature experiments.The effects of different temperatures,thicknesses of coating and substrate are analyzed.Using the two-direction testing,the normal and tangent bonding strengths under high temperature oxidation are investigated.Tests show that the bonding strength of the same TBCs with different thicknesses is very close.The experiments provided many data and reference for failure modelling and aero-engine parts designing with TBC.
