that the pulse current density had a positive effect on the grain refinement. The results of vibrating sample magnetometer (VSM) measurements demonstrated that by increasing the current density, the saturation... by increasing the pulse current density. Also, both the adhesive and abrasive wear mechanisms were observed on the worn surfaces. The abrasive grooves and the amount of wear debris were decreased......

). In these experiments, the waveforms of different electropulsing were similar, and the values of period were same (tp=110 μs), but the values of maximum current density were different. For specimens B, the maximum current density Jmax was 5.26×103A/mm2, and for specimens C, 5.09×103A/mm2. Fig.2 Schematic of experimental arrangement for electro- pulsing treatment Fig.3 Typical waveform......
strategies on the same model, the preliminary overall meshing policy was determined. Then local grid density was explored. The results show that the greater the current density, the more likely...-electrical calculation accuracy of aluminum reduction cells and mesh density CUI Xi-feng, ZHANG Hong-liang, ZOU Zhong, XU Yu-jie, LI Jie, ZHANG He-hui, LAI Yan-qing (School of Metallurgical Science......
,Changsha 410083,China)Abstract:The effect of the current density on the corrosion rate of 22(Ni+Cu)/(NiFe2O4-10NiO) cermet inert anode in Na3AlF6-K3AlF6-AlF3-Al2O 3 melt was studied,and the microstructure of the inert anode tested was also analyzed. The results indicate that with the increase of current density,the factor which is mainly in charge of the corrosion rate of NiFe2O4 based cermet......
