Abstract
As part of advancing oxygen–hydrogen combustion power generation technology, a study was carried out to evaluate the oxidation behavior of a novel developed Ni–Cr–W alloy as the structural material candidate. Tungsten is utilized in the alloy as a solid solution-strengthened element and as an α2-W precipitate former. The examination involved exposing the developed alloy and commercial alloys, Hastelloy X and Nimonic 263, to air and steam environments at 1273 K. The results show a different oxidation behavior of the developed alloy. Considering the air oxidation kinetics, the performance of the developed alloy was on par with that of Hastelloy X and superior to Nimonic 263. A single outer chromia scale was established with an intergranular oxide. Whereas steam exposure resulted in the formation of outer and inner chromia scales with a deeper intergranular oxide penetration. Thicker chromia formation with a lower mass gain indicates the evaporation of chromia under a steam atmosphere.
作为推进氢氧燃烧发电技术的一部分,一项研究对作为候选结构材料的新型 Ni-Cr-W 合金的氧化行为进行了评估。钨作为固溶强化元素和α2-W沉淀前体用于合金中。测试包括将开发的合金和商用合金(哈氏合金 X 和尼莫克 263)暴露在 1273 K 的空气和蒸汽环境中。考虑到空气氧化动力学,所开发合金的性能与哈氏合金 X 相当,而优于 Nimonic 263。形成了单一的外铬垢和晶间氧化物。而蒸汽暴露会形成内外铬鳞,晶间氧化物渗透更深。铬鳞形成较厚,但质量增加较少,这表明铬在蒸汽环境下蒸发。
期刊介绍:
Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
