    摘要： Method for preparing reduced thermal conductivity thermal barrier coating having improved impact resistance for an underlying substrate for high temperature applications. An exemplary method includes depositing a first zirconia-containing ceramic composition having a c/a ratio of about 1.011 to about 1.016 and stabilized in the tetragonal phase by yttria, calcia, ceria, scandia, magnesia, india, lanthana, gadolinia, neodymia, samaria, dysprosia, erbia, ytterbia, europia, praseodymia, and mixtures thereof, and including about 0.3 to about 0.5% by weight lanthana, neodymia, gadolinia, and mixtures thereof The first material forms a high fracture toughness inner layer having a fraction of porosity of about 0.20 or less, and a thickness in the range of from about 0.5 to about 2 mils. The method includes depositing a ceramic material forming an outer thermal insulating layer overlying the inner layer and having a greater fraction of porosity than the inner layer.

This coating comprises an inner high fracture toughness layer nearest to the underlying substrate and having a thickness up to about 5 mils (127 microns) sufficient to impart impact resistance to the thermal barrier coating, and comprises a zirconia-containing ceramic composition having a c/a ratio of the zirconia lattice in the range of from about 1.011 to about 1.016 and stabilized in the tetragonal phase by a stabilizing amount of a stabilizing metal oxide selected from the group consisting of yttria, calcia, ceria, scandia, magnesia, india, lanthana, gadolinia, neodymia, samaria, dysprosia, erbia, ytterbia, europia, praseodymia, and mixtures thereof. The thermal barrier coating further includes an outer thermal insulating layer adjacent to and overlaying the inner layer and comprising a ceramic thermal barrier coating material. The thermal barrier can be used to provide a thermally protected article having a substrate (e.g., metal substrate) and optionally a bond coat layer adjacent to and overlaying the substrate. The thermal barrier coating can be prepared by forming the inner high fracture toughness layer, followed by forming on the inner layer the outer thermal insulating layer.

This coating comprises a zirconia-containing ceramic composition having a c/a ratio in the range of from about 1.0057 to about 1.0123 and stabilized in the tetragonal phase by a stabilizing amount of a stabilizing metal oxide. The coating has a fraction of porosity of from about 0.15 to about 0.25, and an impact and erosion resistance property defined by at least one of the following formulas: (a) I=exp. [5.85−(144×s)−(3.68×p)]; and/or; (b) E=[187−(261×p)−(9989×s)], wherein s=1.0117−c/a ratio; p is the fraction of porosity; I is least about 70 g/mil; and E is least about 80 g/mil. This coating can be used to provide a thermally protected article having a metal substrate and optionally a bond coat layer adjacent to and overlaying the metal substrate. The thermal barrier coating can be prepared by depositing the zirconia-containing ceramic composition on the bond coat layer, or the metal substrate in the absence of the bond coat layer.
