| 目的 对比研究 ZrO2-Y2O3 和 A12O3-TiO2 涂层的抗高温氧化性能。 方法 采用等离子喷涂工艺,以 NiCrAl 为粘接层,在铜合金基体表面分别制备 ZrO2-Y2O3 和 A12O3-TiO2 涂层,测试涂层的显微组织、元素种类及含量、 显微硬度, 并在相同条件下测试涂层的抗高温氧化性能。 结果 ZrO2-Y2O3 和A12O3-TiO2 涂层都具有 明 显 的 层 状 结 构, 涂 层 结 合 紧 密, 内 部 孔 洞 细 小, 显 微 硬 度 分 别 为 423 HV 和628 HV。 这两种涂层都具有一定的抗高温氧化性能,NiCrAl 粘结层是整个涂层最薄弱的环节。 结论 等离子喷涂 ZrO2-Y2O3 涂层的抗高温氧化性能优于 A12O3-TiO2 涂层。 |

| Objective In order to study the oxidation resistance of ZrO2-Y2O3and A12O3-TiO2coatings, ZrO2-Y2O3and A12O3-TiO2coatings with NiCrAl bonding layer were successfully prepared by plasma spraying process. Methods The microstructures, element types and levels and micro-hardness of the different coatings were studied by metallurgical microscopy, scanning electron microscopy ( SEM) , energy dispersive spectrometer ( EDS) and micro-hardness measurement. Oxidation resistance of all the specimens were tested under the same conditions. Results Both ZrO2-Y2O3and A12O3-TiO2coatings had a significant layer structure, good adhesion and low porosity. The micro-hardness of ZrO2-Y2O3and A12O3-TiO2coatings was 423HV and 628HV, respectively. Both ZrO2-Y2O3and A12O3-TiO2coatings had certain oxidation resistance. NiCrAl bonding layer was the weakest part of the whole coatings. Conclusion ZrO2-Y2O3coatings had better oxidation resistance than A12O3-TiO2coatings. |
