    摘要: According to the present invention there is provided a thermal barrier coating wherein multilayers of (I) a ZrO.sub.2 layer containing a luminous activator and stabilized by Y.sub.2 O.sub.3, CaO, MgO or a mixture thereof and (II) a ZrO.sub.2 layer containing a luminous activator different from that used in (I) and stabilized by Y.sub.2 O.sub.3, CaO, MgO or a mixture thereof, or a ZrO.sub.2 layer not containing a luminous activator and stablized by Y.sub.2 O.sub.3 are stacked, and the layers at least under an uppermost layer opposite to a base member to be protected have a total thickness sufficient for exhibiting a thermal barrier effect. The present invention has as its object to provide a thermal barrier coating which allows non-destructive testing to determine whether it has a thickness sufficient for themal barrier effect.
