论文简介
ABSTRACT Thermal barrier coating (TBC) is widely used to lower the temperature of turbine
blades and prevent the premature failure of superalloy substrates. Horizontal and vertical
cracks play key roles in the thermal durability of TBC. It is believed that the surface cracks,
which form perpendicular to the substrate surface, have a promising potential to improve the
thermal life of TBC by increasing coating tolerance to thermal mismatch stresses. In contrast,
as the density of horizontal cracks, especially the interfacial delamination increases TBC ...
