中文摘要:
      目的 研究等离子喷涂 YSZ 涂层的瞬态超高温烧蚀性能。 方法 借助超音速火焰喷涂设备实现超高温高速火焰,对等离子喷涂 YSZ 涂层进行瞬态冲蚀,通过火焰中加送氧化铝颗粒模拟对涂层的高温冲刷。采用常规手段评价涂层的抗瞬态超高温冲蚀性能,并对冲蚀部位进行微观观察,探讨涂层的失效机理。 结果 在 3000 K、不添加砂粒的条件下,火焰冲击 3 s 后钢基体材料表面发生沸腾;喷涂 0.6 mmYSZ 的试样在火焰冲击 60 s 后涂层完好。在 3000 K、添加砂粒的条件下,火焰冲击 3 s 后钢基体材料被冲刷出约 1.0 mm 深坑;喷涂 0.6 mm YSZ 试样的涂层被火焰冲刷剥落,但基体未受明显损伤;喷涂1 mm YSZ 的试样,试验后仍保留部分涂层。 结论 在 3000 K 高温瞬态冲蚀条件下,热喷涂 1 mm 厚YSZ 涂层可对材料表面形成有效防护。
英文摘要:
      Objective To study the transient ultra-high temperature erosion resistance of plasma spray YSZ coatings. Methods The transient ultra-high temperature erosion test on APS YSZ coating was carried out with high temperature and high speed flame generated high velocity oxygen fuel spraying equipment, and the impaction was simulated by feeding the alumina particles. Then the transient ultra-high temperature erosion resistance of coating was evaluated by conventional means. The failure mechanism of the coating was investigated according to the microscopic analysis. Results Under the test condition of 3000 K and no particle addition, the steel substrate boiled after 3 s of flame erosion, while the YSZ coating with 0.6 mm thickness was integral after 60 s of flame erosion. Under the test condition of 3000 K and particles addition, the steel substrate was impacted to generate about 1 mm deep pits after 3 s of flame erosion, the YSZ coating with 0.6 mm thickness was peeled off without substrate damage, and the YSZ coating with 1.0 mm thickness was still partially retained. Conclusion APS YSZ coating with 1.0 mm thickness could protect the substrate effectively from the transient ultra-high temperature erosion at up to 3000 K.
