    摘要:

    燒嘴是水煤漿氣化系統(tǒng)的重要部件。運行過程中的高溫硫化經(jīng)常導致燒嘴提前失效，進而影響設(shè)備的安全穩(wěn)定運行。本文采用等離子噴涂方法制備了Mo為粘結(jié)層的Al-Mo涂層，測量其在973 K, 1073 K and 1173 K的硫化和氧化行為，并與Mo涂層和Inconel合金進行比較。結(jié)果表明Al-Mo涂層的高溫硫化抗力和氧化抗力均優(yōu)于Mo涂層，高溫硫化抗力優(yōu)于Inconel合金。該涂層的提出為噴嘴失效問題的解決提供了便捷、有效的技術(shù)方案。

    Abstract:

    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.
