恒电位电解抛光是以控制阳极电流来进行金相试样电解抛光的。本文用三电极腐蚀法测定了10CrMo910钢在马氏体状态下的各种极化曲线,比较分析了电解液浓度、温度、电位扫描速度对极化曲线的影响。得到良好的抛光效果。一、试验方法试验料为德国进口低碳合金钢10CrMo910,其主要成分为0.1～0.15％C、2～2.5％Cr、0.9～1.1％Mo。材料经1100℃ 30分 Potentiostatic electrolytic polishing is controlled by the anode current metallographic sample electrolytic polishing. In this paper, various polarization curves of 10CrMo910 steel in the martensitic state were measured by the three-electrode etching method. The influence of electrolyte concentration, temperature and potential scanning speed on the polarization curve was analyzed. Get a good polishing effect. First, the test method Test materials for the German imports of low-carbon steel 10CrMo910, the main components of 0.1 ~ 0.15% C, 2 ~ 2.5% Cr, 0.9 ~ 1.1% Mo. Material by 1100 ℃ 30 minutes
