| 目的 对航空发动机热端部件表面长效防护涂层W-200进行改进，研制高温稳定性更好且不易崩瓷的高温合金表面新型高温陶瓷涂层，解决W-200涂层在部分高温合金表面暴露出的易崩瓷、剥落问题。方法 通过调整膨胀系数、软化温度、析晶温度，来研制新型耐高温玻璃和耐高温填料，并制备新的高温陶瓷涂层浆料。结果 所研制的新型高温陶瓷涂层W-400能够满足在高温合金表面1 150~1 230 ℃顺利烧结，且具有更大的膨胀系数，可与高温合金基材的膨胀系数更匹配。同时，W-400的析晶温度区间为868~ 1 213 ℃，在析晶温度区间，涂层较W-200具有更好的高温稳定性，以及更优的抗热震、抗剥落性能，并可覆盖实际应用的温度范围。结论 新型高温陶瓷涂层W-400解决了目前W-200高温陶瓷涂层在航空发动机高温合金热端部件表面烧结后易崩瓷的问题。根据本项目的研究基础，对未来可研制出能够在其他金属表面1 250~1 400 ℃顺利烧结的耐温更高的新型高温陶瓷涂层提供了可能性。 |

| The work aims to improve the long-term protective coating W-200 on the hot end part surface of aero-engine, and explore a new high-temperature ceramic coating on the superalloy surface with better high temperature stability and not easy to collapse so as to solve the problem of brittle porcelain and peeling exposed by W-200 coating on the superalloy surface. By adjusting expansion coefficient, softening temperature and crystallization temperature, new high-temperature resistant glass and filler were developed, and new high-temperature ceramic coating slurry was prepared. The new high-temperature ceramic coating W-400 could be successfully sintered on the superalloy surface at 1 150~1 230 ℃, and had a larger expansion coefficient, which could better match the expansion coefficient of superalloy substrate. At the same time, the crystallization temperature of W-400 was about 868~1 213 ℃, and the coating had better high-temperature stability, thermal shock resistance and resistance than W-200 in the crystallization temperature range. The new high-temperature ceramic coating W-400 solves the problem that W-200 high-temperature ceramic coating is likely to collapse after sintering on the hot end superalloy alloy parts surface of aeroengine. According to the research foundation of this project, it is possible to develop a new type of high-temperature ceramic coating with higher temperature resistance that can be successfully sintered on other metal surfaces at 1 250~1 400 ℃ in the future. |
