China 25(2015) 1692-1698 Electrochemical behavior of Pb-Ag-Nd alloy during pulse current polarization in H2SO4 solution Xiao-cong ZHONG1, Xiao-ying YU1, Liang-xing JIANG1... June 2014; accepted 9 September 2014 Abstract: The anodic layer and oxygen evolution behavior of Pb-Ag-Nd alloy during pulse current polarization and constant current polarization in 160 g/L H2SO4......
献标识码: A Effect of pulse frequency on pulsed electric current sintering process of iron-based powders LONG Yan, LI Yuan-yuan, LI Xiao-qiang, QIU Cheng, LUO Zong-qiang (School of Mechanical... temperature of 1100℃. Key words: iron-based powders; pulsed electric current sintering; pulse frequency; microstructure; mechanical property 20世纪80年代以来, 脉冲电流烧结(pulsed electric current......
and current densities. Compared with direct current electrodeposition, the thicker coating and finer grains can be obtained at lower temperature and current density by pulse electrodeposition. The electrodepostion velocity is about 0.24 ?m/min, which is faster than that by direct current electrodeposition. In 1 mol/L H2SO4, 3.5% NaCl and 10% NaOH solution, corrosion potential of Cr pulse-deposited film......

-W-P-SiC composite coatings have been studied. The results indicate that pulse current can improve the deposition rate of RE-Ni-W-P-SiC composite coatings; W, P, and SiC contents in the coating... with the increase of duty cycle, W content reaches the lowest value, and P content reaches the highest value at r=0.4; pulse current and RE can lend to smaller size of the crystalline grains; however......
, Harbin 150001, China)Abstract:Al2O3/Ni-Co composites with different additives and Al2O3 particles were fabricated by pulse current electrodeposition. The effects of different additives and Al2O3..., when the saccharin was used as additive.Key words:additives; composites; mechanical properties; pulse current electrodeposition......
in the strategy of controlled pulse key-holing. For any welding condition, a peak current value large enough should first be applied to assure the penetration and formation of keyhole. Once keyhole forms... To validate the system and the control strategy, controlled pulse key-holing welding experiments were conducted. The welding conditions were as follows: peak current IP=160 A, and base current IB=80......
