Most infants and children implanted with left ventricular assist devices (LVADs) are bridged to cardiac transplantation. Prioritizing recovery may decrease this trend. Patients were treated with LVAD ventricular decompression, medical heart failure t

Five production thermal barrier coatings were thermally cycled between room temperature and 1121°C (2050°F) to determine relative spallation life. Bond strength measurements were made using a modified ASTM direct pull-test. Bond stress measurements

Thermal barrier coatings, used extensively on hot section gas turbine engine components, weaken and spall after repeated thermal exposure during normal engine operation. A new technique has been developed, involving the use of vacuum impregnation of

The spallation failure of a commercial thermal barrier coating (TBC), consisting of a single-crystal RENE N5 superalloy, a platinum aluminide (Pt-Al) bond coat, and an electron beam-deposited 7 wt pct yttria-stabilized zirconia ceramic layer (7YSZ),

Thermal barrier coatings (TBCs) have been extensively used in aircraft engines for improved durability and performance for more than 15 years. In this study, chevron-notched sandwich specimens proposed recently by Shaw are chosen for the study of the

The failure mode for thermal barrier coatings in gas turbine engines is spallation at or near the ceramic to metal interface. We propose that the two most important factors leading to this failure are the change in the bond strength and bond stress w
