Electropolishing parameters of NiTi alloy MIAO Wei-dong(缪卫东)1, MI Xu-jun(米绪军)2, WANG Xin-lu(王新录)1, LI Hua-chu(栗华矗)1Li Rui (李锐) 1. General Research Institute for Nonferrous Metals, Beijing 100088... in NiTi alloy in several fields for its special characteristics, but its essential details and electropolishing mechanism have not been reported yet as a demand from business competition, which......
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......
