亚微米电解加工的试验研究
Experimental study on submicron electrochemical machining
摘要
Abstract
In order to improve the stability of Ag nanowires in submicron electrochemical machining,Au is sputtered on the surface of Ag nanowires.The results of stability experiments of Ag nanowires show that the stability of Ag nanowires increases with the increase of the thickness of sputtering layer.However,when the sputtering layer is too thick,Ag nanowires are bent.When the thickness of the sputtering layer is about 55 nm,the submicron tool electrode dissolves in electrochemical machining due to loose sputtering layer,while it is bent because of large internal stress when the thickness of the sputtering layer is about 310 nm.Therefore,the submicron tool electrode with the thickness of the sputtering layer of about 150 nm is appropriate to submicron electrochemical machining.In the electrolyte with 0.1 mol/L H2SO4,by using the pulse generator with 50 ns in period,6 ns in pulse on-time and 4 V in voltage,a submicron groove with the length of 30 μm,depth of 80 nm,minimum bottom width of 450 nm and maximum entrance width of 1 μm is prepared suecessfully in the surface of high-temperature-alloys workpiece.关键词
