摘要
在５％高氯酸酒精溶液中采用双喷电解抛光技术制备了２Ｃｒ－１Ｍｏ钢薄膜样品，试验了电解抛光温度、电压和电流密度对薄膜试样质量的影响，通过透射电镜分析，确定出当温度为－４０℃，电压为６０Ｖ，电流密度为４．２ｍａＡ／ｍｍ２时，可制出理想的电镜薄膜试样．
With the double spout electrolytic polishing device and H-800 TEM.Studies the effects of electrolytic polishing parameters on the thin foil specimen preparation of 2 Cr-1Mo steel, It is concluded that during the electrolytic polishing process, when temperature is -40℃, voltage is 60V,electric current density is 4.2mA/mm2, an ideal metal thin foil specimen can be obtained.
