卤素效应,其中涉及的表面富集的合金与卤素元素,导致改善的抗氧化性,使用模型镍基Ni-Cr-Al合金进行了评估。研究的合金的组成不同的方式,产生亚临界,边界线和保护性的内在氧化行为,从能够形成连续的Al 2 O3规模的立场。氟离子注入允许一个明确的表面掺杂的合金。结果发现,这种掺杂可以促进在900和1,000 °C下在干燥和含蒸汽气氛中氧化期间形成保护性Al 2 O3垢。具体而言,有益的卤素效应通过降低Al 2 O3氧化皮形成所需的Ni-Cr-Al合金中的临界Al含量来表现。
The halogen effect, which involves the surface enrichment of an alloy with a halogen element to result in improved oxidation resistance, was assessed using model Ni-based Ni–Cr–Al alloys. The alloys studied varied in composition in a manner that produced sub-critical, borderline and protective intrinsic oxidation behaviours from the standpoint of being able to form a continuous Al2O3scale. Fluorine-ion implantation allowed for a well-defined surface doping of the alloys. It was found that this doping could promote protective Al2O3-scale formation during oxidation at 900 and 1,000 °C in both dry and steam-containing atmospheres. Specifically, the beneficial halogen effect was manifested by lowering the critical Al content in Ni–Cr–Al alloys needed for Al2O3-scale formation.
