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。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, 1073和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。
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 were deposited by plasma spraying with a Mo bonding layer.The sulfidation and oxidation behavior of the Al-Mo coatings was studied and compared with those of Mo coatings and Inconel 600alloy at 973,1073 and 1173K.Results show 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 600alloy.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.
