R. Kowalewski et H. Mughrabi, INFLUENCE OF A PLASMA-SPRAYED NICRALY COATING ON THE LOW-CYCLE FATIGUE BEHAVIOR OF A DIRECTIONALLY SOLIDIFIED NICKEL-BASE SUPERALLOY, Materials science & engineering. A, Structural materials: properties, microstructure and processing, 247(1-2), 1998, pp. 295-299
In this work the high-temperature low-cycle fatigue behaviours of the
NiCrAlY-coated, directionally solidified nickel-base superalloy CM 247
LC and the bulk NiCrAlY coating material PCA-1 have been investigated
. Attention has been focused on the temperature dependence of the fati
gue life endurance of the coating-substrate composite and the bulk coa
ting material in the temperature range 400-1000 degrees C. It could be
shown that the fatigue properties of the bulk NiCrAlY coating materia
l essentially control the fatigue life of the coating-substrate compos
