Ceramic-coated member and production method thereof

摘要

A ceramic-coated member is configured by laminating at least a thermal stress relieving layer 22 and a thermal barrier layer 23 in this order on a base material 20 of metal or ceramic. A density of zirconium oxide forming the thermal stress relieving layer 22 decreases continuously and a density of hafnium oxide forming the thermal barrier layer 23 increases continuously from the thermal stress relieving layer 22 toward the thermal barrier layer 23 in a boundary portion 24 and its neighborhood between the thermal stress relieving layer 22 and the thermal barrier layer 23.
