- the materials listed in Table 15 above were synthesized.
- oxides, hydroxides or carbonates of the respective constituent elements were selected as starting materials, weighed so as to have a predetermined ratio, and mixed in a solid phase using a ball mill. After the mixed powder was dried, it was calcined at 140 ° C. When the obtained calcined powder was identified by powder X-ray diffraction, it was confirmed that unreacted raw material components did not remain, and that all samples were in a single phase. For each of the peaks, the peaks were examined in detail, and a peak shift was observed in a certain direction, confirming that the added solid solution component was surely dissolved in the crystal.
- the thermal conductivity of these materials at room temperature and at 100 ° C can be estimated to be lower than that of zirconia, and they are suitable as thermal barrier coating materials. It is thought that it is.

- the material whose thermal expansion coefficient was larger than that of zirconia and whose thermal conductivity was smaller than that of zirconia in the previous Example 1 is suitable as a thermal barrier coating material. Verification test was conducted. For the verification, the operating condition of the gas turbine was assumed as the application target, the thermal stress applied at the time of starting and stopping as the state where the largest stress was applied was considered, and the fatigue cycle caused by this thermal stress was examined elementally. The test was performed.
- the heat-resistant alloy was cut out into a disc shape and used as a test piece base material.

- a pond coat layer made of oNiCrA1Y alloy is formed by low-pressure plasma spraying, and a ceramic layer (thermal barrier coating) is formed on top of this CoNiCrAlY alloy bond coat by atmospheric plasma spraying.
- the test pieces were formed by laminating layers consisting of materials) to form a thermal barrier coating.
- the thickness of the pound coat layer (CoNiCrA1Y alloy film) was 0.1 mm, and the thickness of the ceramic layer was 0.5 mm.
- a large infrared lamp is condensed and heated on the surface of the thermal barrier coating film side of this test piece, and when the surface temperature reaches a predetermined temperature, the light from the lamp is blocked by a shutter Then, a heat cycle test was performed in which the heating Z cooling cycle was repeated in which the shutter was opened and heated again when the temperature was cooled to a predetermined temperature.
- the specimen was heated as an accelerating condition. Cooling air at about 120 ° C was injected from the nozzle to the opposite surface to be cooled to cool the entire test piece. As a result, the test specimen is cooled to almost 0 ° C centering on the surface on the side opposite to the thermal barrier coating film, so that the test specimen is always heated except for the surface on the thermal barrier coating film side when heated by the red tad wire lamp. The whole will be cooled. By intentionally applying such a temperature difference, a very large thermal stress is applied to the test piece, centering on the film interface. This test was conducted until the thermal barrier coating surface was peeled off visually.
- the thermal cycle test was performed on samples coated with a thermal barrier coating film made of S r 2 N b 2 0 7 .
- the maximum temperature of the heated surface of the test piece (the surface of the thermal barrier coating film) was set to 144 ° C, and the maximum interface temperature (the maximum temperature of the interface between the thermal barrier coating film and the substrate) was repeated at 850 ° C.
- the heating time was repeated for 1 minute and the cooling time was repeated for 1 minute.
- Table 18 shows the results of this heat cycle test. For comparison, the case of a thermal barrier coating film of 3 YSZ is also shown. Table 18
- a thermal barrier coating film having a high coefficient of thermal expansion and a low thermal conductivity can be formed. If such a coating film is used for a heat-resistant protective film of a gas turbine or the like, excellent heat resistance and durability can be obtained, and thus the combustion gas can be obtained. C which can also to a high temperature of scan obtaining Antofagasta one bottle readily adaptable high performance
