Zoric et al[6] ever studied the current distribution in prebake... and spike. 4.1 Jy in metal pad 4.1.1 Normal cell conditions (zero ledge length) Current density (Jy) is shown in Fig.3 and J distribution in Y-Z plane is shown in Fig.4. Fig.3 Jy......
J. Cent. South Univ. Technol. (2011) 18: 165-170 DOI: 10.1007/s11771-011-0675-9 Calculation of optimal current density of double side permanent magnet linear synchronous motor JANG Ki-Bong... of design method considering a coil temperature to maximize the thrust density of a double side coreless permanent magnet linear synchronous motor (PMLSM) was presented. The optimal current density where......
" case, the current density is higher than that in the "with die" case. And the higher current density has enhanced mass transport. The temperature has also an effect on the location of failure. Not only... temperature distribution is a major benefit of this technique. It should also be pointed out that the current can play an additional role besides providing Joule heating. Recent investigations have......
University Press and Springer-Verlag Berlin Heidelberg 2011 Abstract: The influences of the mask wall angle on the current density distribution, shape of the evolving cavity and machining accuracy were investigated in electrochemical machining (ECM) by mask. A mathematical model was developed to predict the shape evolution during the ECM by mask. The current density distribution is sensitive to mask wall......

Influence of current density on nano-Al2O3/Ni+Co bionic gradient composite coatings by electrodepositionYan Liu1),Luquan Ren1),Sirong Yu2),and Zhuwu Han1) 1) The Key Laboratory of the Ministry... by different current densities,and the 2-D and 3-D morphologies of the surface coatings were observed. The result indicated that the 2-D structure became rougher and the 3-D surface density of apices became......
Effect of the current density on electrodepositing alpha-lead dioxide coating on aluminum substrate Yuandong CAO1,Xianwan YANG1,Zhongcheng GUO1,Burning CHEN1,Hui HUANG1 (1.Faculty of Materials... electrodes are analyzed by using SEM, EDS, XRD, Tafel plot, linear sweep voltammetry (LSV) and A.C. Impedance. A compact and uniform layer of lead dioxide was obtained at the current density of 3 mA-cm......
