Spallation thermal barrier coatings

M. GeU, L.D. Xie, E.H. Jordan, N.P. Padmre, Mechanisms of spallation of solution precursor plasma spray thermal barrier coatings. Surf. Coat. Techol. 188—189 (2004) 101—106. [Pg.286]

Figure 14.9 shows the oxidation behaviour of Ti-45Al-8Nb specimens coated with different aluminide layers and TBCs under cyclic and quasi-isothermal oxidation conditions. For comparison, mass change data of preoxidised specimens with TBC are included. No spallation of the thermal barrier coatings was observed after 1000 cycles at 900 C for specimens coated with the two types of aluminides investigated. Drops in mass change... [Pg.255]

If cracks are deflected toward parallel direction to the surface, the cracks coalesce and results in spallation and thus in the degradation of the heat insulating property of a thermal barrier graded coating. [Pg.147]
