Comparison of structure and physical fields in 400 kA aluminum reduction cellsDING Ji-lin(丁吉林), LI Jie(李劼), ZHANG Hong-liang(张红亮), XU Yu-jie(徐宇杰), YANG Shuai(杨帅), LIU Ye-xiang(刘业翔) (School... shows that all studied cells can satisfy with the physical field requirement, and the commercial applications also verify that the 400 kA cells have become the product of the mature and world’s......
is strongly dependent on magnesium content. Corrosion potential decreases with increasing magnesium content, whereas current density increases up to 15% magnesium content, and passivity region was found only in Zn-Mg coatings. Key words: magnesium; zinc; corrosion resistance; physical vapor deposition; coating; electrochemistry 1 Introduction Metallic coatings containing zinc (Zn) have been commercially......
Preparation of Ti-Al alloy sheet by electron beam physical vapor deposition MA Li(马李), HE Xiao-dong(赫晓东), SUN Yue(孙跃) Center for Composite Material, Harbin Institute of Technology, Harbin 150001... sheet with dimension of 450 mm×450 mm×0.2 mm was prepared by electron beam physical vapor deposition(EB-PVD) technology. The surface and cross-section pattern of as-deposited sample were studied by SEM......
was contrasted; meanwhile, the different of displacement phenomena and mechanism between activating microbial in model and flooding with fermentation broth was studied intensively for illustrating the unique..., such as chemotaxis and in-situ metabolism, which is absent in chemical displacement. In general, the oil recovery in the whole model increases by 11.2%-13.5%. Key words: physical simulation; microscopic model......
