||This paper mainly take will study the high-voltage 520Vf anode aluminum foil as the focus, the distinction includes different Cu, Pb, Fe, Si rare element carries on aluminum foil after electrochemistry etching, its corrosion organization and appearance regarding surface area increment influence.|
This experiment first uses the permanent electric potential meter survey the environment, electric potential - time and electric potential - corrosion electric current relations chart. Affiliation by the electric potential, the electric current, the time change extrapolation corrosion response carries on when situation. Receives discusses the different rare element (Cu, Pb, Fe, Si) the anode aluminum foil after corrodes influence the action. The actual electrochemistry etching with high-voltage 520Vf anode aluminum foil, defers to EIAJ again the standard does to the aluminum foil turns into processing, and distinction survey it capacitance, the weight loss ratio,tensile strength,bending stress. Again coordinates cube ratio, to analyze the tapping quantity, the oxide thickness at surface, separately performs to analyze. Finally (OM) (SEM) will corrode again using the optics microscope with the scanning type electron microscope previews does the section, the surfacel observation understands the pit,tnuuel distributed condition.
May know by the experimental result, differently contains the copper quantity previews by way of the permanent electric potential meter survey, may know along with contains the copper quantity the increase its collapse electric potential also reduces along with it, along with contains copper quantity the increase its weight loss ratio has the increase the tendency, how much cube ratio with contains the copper quantity has the direct ratio the tendency. Regarding contains the lead quantity the discussion, along with contains the lead quantity the increase its collapse electric potential also reduces along with it, along with contains lead quantity the increase its weight loss ratio also has the slightly increase the tendency, cube ratio along with contains the lead quantity the increase has the drop the tendency. Regarding hard, the silicon content discussion, the collapse magnitude of current can along with the iron, the silicon content increase drops, cube ratio along with hard, the silicon content increase has the drop the tendency. From this the experiment hopes can further understand the rare element uses the anode foil to the high pressure the influence.
