TC4钛合金表面纳米级磁力研磨的实验研究
Experimental study on nanoscale magnetic abrasive finishing of TC4 titanium alloy surface
摘要
Abstract
Dual-pole Magnetic Abrasive Finishing(DMAF)method has been proposed for achieving a smooth surface on TC4 ti-tanium alloy.Initially,9 different combinations of magnetic poles were designed,and ANSYS Maxwell finite element software was used to simulate the distribution of magnetic field lines and magnetic induction intensity.Based on the results of the simulation,the best magnetic pole combination was determined.The processing parameters of multi-stage DMAF were optimized through com-parative experiments of major single factors.Finally,the abrasive combinations for the three polishing stages were obtained as fol-lows:#100 electrolytic iron powder+#2000 white corundum,#200 electrolytic iron powder+#8000 white corundum,and #450 e-lectrolytic iron powder+#w1 diamond;the magnetic pole gap is 5 mm,the speed of magnetic pole spindle is 300 r/min,and the abrasive mass ratio is 2∶1.It is indicated in the experiment that after 30 minutes of polishing on TC4 titanium plates using the multi-stage DMAF,the average surface roughness Sa was reduced from the initial 0.442 μm to 8 nm,and a nano-level mirror pol-ishing effect has been essentially achieved in the polishing area.关键词
