Trans. Nonferrous Met. Soc. China 22(2012) s820-s824 Microstructure of fast tool servo machining on copper alloy Hong LU1, Soo-chang CHOI2, Sang-min LEE1, Deug-woo LEE3 1. Department of Nano Fusion... performance of a piezoelectric-assisted FTS on copper alloy was evaluated. The results indicate that the quality of the microstructure depends mainly on two important factors: the cutting speed......
Purification mechanism of copper electrolyte by As(Ⅲ) XIAO Fa-xin(肖发新)1, 2, ZHENG Ya-jie(郑雅杰)1, WANG Yong(王 勇)1, JIAN Hong-sheng(简洪生)1, HUANG Xing-guan(黄兴远)2, MA Yu-tian(马玉天)1 1. School...)-O-Sb(OH)3)3]-O-Sb(OH)2·xH2O. The structure analysis shows that the copper electrolyte can be purified by As(Ⅲ) because the antimony arsantimonate precipitate forms. Key words: arsenic; purification......
