指導教授 : 薛文景 周瑞崇

摘要


本研究主要是使用鹽霧試驗來,測試形成多孔質氧化鋁的試片的抗腐蝕性。實驗使用三組濃度1Vol%、5 Vol%和10 Vol%的磷酸(Phosphoricacid)溶液當作陽極處理的電解液,首先將裁切好的鋁試片分別經過丙酮、酒精、水在超音波震盪機震盪10分鐘後,再把試片置於陽極,白金片置於陰極,用四組電壓110V、130V、150V和170V 進行30分鐘的陽極處理,再經由0.5M NaOH移除表面不規則的氧化膜,最後進行第二次的陽極處理法4小時,表面會生成一層緻密的六角形蜂巢結構的氧化膜,總共12組試片。再將12組試片做SEM、高組計和耐電壓測試儀測驗,最後再做鹽霧試驗找出多少電壓和濃度的磷酸溶液的試片有最好抗腐蝕性。結果是5Vol%磷酸的150V和170V的試片,10Vol%磷酸的150V的試片的抗腐蝕性最好。

This study is the use of salt spray test, the test form a porous alumina specimen corrosion resistance. Experiments using three sets of concentration 1Vol%, 5 Vol% and 10 Vol% phosphoric acid (Phosphoricacid) as anodizing electrolyte solution, first cut good aluminum specimens, respectively, after acetone, alcohol and water in the ultrasonic vibration machine after 10 minutes, the shock, then the specimen is placed an anode, a cathode placed on platinum sheet, with four groups of voltage 110V, 130V, 150V and 170V for 30 minutes, anodized, 0.5M NaOH and then through the oxide film to remove surface irregularities Finally the second anodic treatment for 4 hours the surface will generate a hexagonal honeycomb structure of dense oxide film, a total of 12 groups of test pieces. 12 groups of test pieces and then do SEM, high group count and voltage resistance tester tests, and finally do find out how much salt spray test voltage and the concentration of phosphoric acid solution specimen has the best corrosion resistance. The result is 5Vol% phosphoric acid test piece 150V and 170V, 10Vol% phosphoric acid test strip 150V best corrosion resistance
