J. Cent. South Univ. (2017) 24: 1627-1636 DOI: 10.1007/s11771-017-3568-8 Metallogenic mechanism of Pingguo bauxite deposit, western Guangxi, China: Constraints from REE geochemistry and multi... by the loss of diffluent elements (e.g., Si and S) and enrichment of stable elements (e.g., Al and Fe) in the surface environment. Among the rest, the migration mechanism of iron during the evolutionary......

Cavitation erosion behavior of WC coatings on CrNiMo stainless steel by laser alloyingXiao-bin Zhang1,2),Chang-sheng Liu1),Xiao-dong Liu1),Jiang Dong1),Bo Yu3) 1) School of Materials and Metallurgy... technique. Phases in the layers were investigated by X-ray diffraction (XRD) analysis and surface morphologies after cavitation erosion were observed with the help of scanning electron microscopy (SEM......
Preparation and Arc Erosion Resistance of C_f/Cu Composite by Vacuum Melting Infiltration张华煜1,LIU Yiwen2,ZHAO Xianling1,LUAN Xingang21. College of Material Science and Engineering, Taiyuan University... erosion rate of Cf/Cu composite was investigated in vacuum. The results showed that the Tiand Cr could improve the wettability between Cu and C/C preform and the infiltration ability of Cu into C/C......

were characterized, and the arc erosion mechanism of AgSnO2 contact materials was discussed. The results show that fine SnO2 particle is beneficial for the improvement of the relative density... benign and remarkable performances [7-12], the arc erosion mechanism of AgSnO2 contact material is still obscure so far. RIEDER and WEICHSLER [13] thought that the arc erosion is strongly influenced......
