中文摘要:
      烧嘴是水煤浆气化系统的重要部件。运行过程中的高温硫化经常导致烧嘴提前失效,进而影响设备的安全稳定运行。本文采用等离子喷涂方法制备了Mo为粘结层的Al-Mo涂层,测量其在973 K, 1073 K and 1173 K的硫化和氧化行为,并与Mo涂层和Inconel合金进行比较。结果表明Al-Mo涂层的高温硫化抗力和氧化抗力均优于Mo涂层,高温硫化抗力优于Inconel合金。该涂层的提出为喷嘴失效问题的解决提供了便捷、有效的技术方案。
The high-temperature sulfidation and oxidation behavior of plasma-sprayed Al-Mo coatings
英文关键词:Al-Mo coating  plasma spraying  high temperature sulfidation.
英文摘要:
      Gas burner is the key component of coal-water slurry gasifier system. However, due to the sulfidation at high temperature, gas burner often fails in advance, which affects the stable operation of the system. In this work, Al-Mo coatings are deposited by plasma spraying with a Mo bonding layer. The sulfidation and oxidation behavior of the Al-Mo coatings is studied and compared with those of Mo coatings and Inconel 600 alloy at 973 K, 1073 K and 1173 K. It is found that both the high-temperature sulfidation resistance and the high-temperature oxidation resistance of Al-Mo coatings are superior to those of Mo coatings. The high temperature sulfidation resistance of coatings is better than that of Inconel 600 alloy. Plasma-sprayed Al-Mo coatings with a Mo bonding layer are promising candidates for the corrosion protection of steels in a sulfur/oxide-rich atmosphere.
