摘要

研究了Ni-35Fe和Ni-65Fe合金在含有0%、0.1%和1% NaCl-KCl-CaCl2盐混合物的砂中在480℃空气中的高温腐蚀行为。氧化铁皮的生长速度受Ni-35Fe和Ni-65Fe合金基体内扩散的控制。在含盐量为0.1%和1%的砂中观察到铁的内氧化和氯化反应。氯盐增加了Ni-35Fe和Ni-65Fe合金表面氧化铁垢的生长速度。

High-Temperature Corrosion Behavior of Ni-35Fe and Ni-65Fe Alloys Embedded in Silica Sand Containing NaCl-KCl-CaCl2 Salts at 480 °C

The high-temperature corrosion behavior of Ni-35Fe and Ni-65Fe alloys embedded in sand containing 0%, 0.1%, or 1% of NaCl-KCl-CaCl₂ salt mixture at 480 °C in air was investigated. The growth rate of the iron oxide scale was found to be controlled by diffusion within the Ni-35Fe and Ni-65Fe alloys matrix. Internal oxidation and chlorination of Fe were observed in sand with salt contents of 0.1% and 1%. Chloride salts increased the growth rate of the iron oxide scale on the Ni-35Fe and Ni-65Fe alloys.

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.
