Preparation and performance of fluorescent sensing coating for monitoring corrosion of Al alloy 2024 LI Song-mei(李松梅), ZHANG Hong-rui(张洪瑞), LIU Jian-hua(刘建华) School of Materials Science.... After a certain time, when the samples of Al alloy 2024 coated with PF-acrylic paint were immersed in 1 mol/L NaCl solution, fluorescence quenching spots can be seen with unaided eyes......
alloy has been studied in molten fluoride system consisting of fluorides of both zirconium andtitanium dissolved in FLINAK(KF:NaF:LiF=42.0:11.5:46.5 mol).A coherent dense deposit of the alloy with a smooth sur-face is obtained on different material substrates.X-ray diffraction has demonstrated that the alloy deposit is a Ti-Zr solid solu-tion with Ti mainly and its preferred orientation is strongly......
Influences of melt treatment on grain sizes and morphologies of AZ91D alloy QI Xiang-chao(齐祥超)1, TANG Jing-lin(唐靖林)1, 2, LI Shuang-shou(李双寿)1, 2, ZENG Da-ben(曾大本)1 1. Department of Mechanical...) on the microstructures of AZ91D alloy were explored experimentally. The results indicate that the micron carbon powders inoculation processing with 0.1% (mass fraction) addition level makes the grain size......
