摘要

通过磁控溅射法在不同偏置电压（0 V 至 -500 V）下沉积在包壳管外表面的铁铬铝铍镀层在氧气饱和和氧气贫乏的 LBE 中于 550 - 600 °C 下腐蚀了 500 - 1000 h。随着偏压的增加，涂层从柱状晶变成了等轴晶。偏压的降低使耐腐蚀性得到改善。讨论了支配 FeCrAlY 涂层微观结构和耐腐蚀性演变的基本过程。

Effect of bias voltage on the microstructure and LBE corrosion resistance of the FeCrAlY coating

FeCrAlY coatings deposited on the outer surface of the cladding tube by the magnetron sputtering with varying bias voltages (0 V to -500 V) were corroded at 550 – 600 °C in oxygen-saturated and oxygen-poor LBE for 500 – 1000 h. The increased bias voltage led to the Al content decreased and the Y content increased. The coating changed from columnar crystals to equiaxed crystals with the increase of bias voltage. The decreased bias voltage makes an improved corrosion resistance. The fundamental process governing the evolution of microstructure and corrosion resistance in the FeCrAlY coatings was discussed.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
