| 中文摘要: |
| 采用HVOF 技术喷涂金属粘结层NiCrAlY 作为底层,采用APS 技术喷涂纳米氧化锆陶瓷层作为面层,制备高性能热障涂层。设计正交试验优化HVOF 和APS 工艺,分析了优化工艺制得的热障涂层的微观形貌及性能。分析表明,NiCrAlY 涂层孔隙率小于2%,纳米氧化锆涂层孔隙率为15%。通过胶膜法测得纳米氧化锆热障涂层喷涂态的结合强度为30.4 MPa,且涂层经1100 益水淬50 次后表面无宏观裂纹,热生长氧化层为致密的Al2O3。 |
| 英文摘要: |
| High performance thermal barrier coating was composed of bond coat NiCrAlY and top coat nanostructural zirconia. NiCrAlY coating was fabricated by high velocity oxygen fuel spraying, while nanostructural zirconia coating was fabricated by atmosphere plasma spraying. Both processes were optimized by means of orthogonal design. The morphology and property of the thermal barrier coating prepared by these optimal processes were analyzed. The results indicate that the porosities of NiCrAlY bond coat and nanostructural zirconia top coat are less than 2% and about 15% , respectively. The tensile samples are bonded using solid membrane adhesive. The bond strength value of the sample measured by tensile adhesion test is about 30. 4 MPa. The thermal shock test is performed by water quenching method. The sample is heated in furnace at 1100 益and then quenched into ambient water. The thermally grown oxide of thermal barrier coating after 50 cycles is compact Al2 O3 . |
