| 目的 研究真空电弧镀方法制备的超高温金属涂层HY11在1200 ℃下的高温氧化行为。方法 用真空电弧镀技术（AIP）在单晶镍基高温合金DD6上制备超高温金属涂层HY11，采用HB 5258循环氧化方法进行1200 ℃循环氧化试验，通过试验过程中试样质量变化评价涂层氧化寿命。通过扫描电镜（SEM）分析氧化后的试样显微形貌，用X-射线衍射仪分析涂层材料的相结构，通过氧化速率对涂层材料抗氧化性能进行表征。结果 采用单靶真空电弧镀技术制备的HY11涂层，经过1050 ℃真空条件下扩散2 h，涂层厚度为50~60 ?m，扩散区厚度为10~15 μm，涂层微观组织均匀致密，涂层合金界面清晰平整。DD6合金的1200 ℃循环氧化寿命仅仅为4 h，HY11涂层在1200 ℃的循环氧化寿命近300 h。沉积态涂层HY11相结构主要以Al2O3和Ni3Al为主。氧化后涂层材料表面形成的氧化膜以Al2O3为主。结论 HY11涂层在1200 ℃的循环氧化寿命为298 h，极大地提高了DD6合金在1200 ℃的循环氧化寿命。 |

| Objective To observe the high temperature oxidation behaviors of superhigh temperature metal coating Y11 made through vacuum arc ion plating at 1200 ℃. Methods HY11 coating was deposited by AIP on single crystal nickel-base superalloy DD6. The cyclic oxidation test was carried out at 1200 ℃ through HB5258 cyclic oxidation. The oxidation life of the coating was assessed through mass change during test. The microstructure of the sample after oxidation was analyzed with SEM. The phase structure of the coating was analyzed with X-RAY diffractometer. The oxidation resistance of the coating was characterized by scanning electron microscopy and X-ray diffraction. Results For HY11 coating made of single target ARC ion plating after two hours of diffusion in vacuum at 1050 ℃, the thickness of coating was 50~60 ?m, the thickness of diffusion zone was 10~15 μm. Microstructure of the coating was uniform and dense. The alloy interface of the coating was clear and flat. The cyclic oxidation life of DD6 alloy at 1200 ℃ was only 4 h and that of HY11 coating was nearly 300 h. The as-deposited coating was mainly composed of Al2O3 and Ni3Al. The coatings material was composed of Al2O3 after oxidation in air at 1200 ℃. Conclusion The cyclic oxidation life of HY11coatings is 298 h at 1200 ℃. The cyclic oxidation life of DD6 alloy at 1200 ℃ is improved significantly. |
