The role of using pulsed laser deposition (PLD) as a means for applying alumina (Al₂O₃) and chromia (Cr₂O₃) coatings to the HAYNES® 214® alloy was investigated to provide oxidation resistance in air at 800 °C. Using various material characterization techniques, it was found that an amorphous Cr₂O₃ coating approximately 150 nm thick could promote and maintain the formation of a protective α-Al₂O₃ scale for durations of at least 100 h of exposure. The Cr₂O₃-coated alloy also provided superior protection under thermal cycling conditions. The Al₂O₃-coated alloy provided results comparable to the uncoated alloy in all isothermal oxidation tests performed; however, it appeared to provide some benefit under thermal cycling conditions.

研究了使用脉冲激光沉积 (PLD) 作为在 HAYNES® 214® 合金上涂覆氧化铝 (Al ₂ O ₃ ) 和氧化铬 (Cr ₂ O ₃ ) 涂层的方法，以提供 800 °C 空气中的抗氧化性。使用各种材料表征技术，发现大约150 nm厚的无定形Cr ₂ O ₃涂层可以在至少100小时的暴露持续时间内促进和维持保护性α-Al ₂ O ₃氧化皮的形成。Cr ₂ O ₃涂层合金还在热循环条件下提供卓越的保护。在进行的所有等温氧化测试中， Al ₂ O ₃涂层合金提供的结果与未涂层合金相当。然而，它似乎在热循环条件下提供了一些好处。
