    摘要:

    研究了AM50裸鎂合金及在裸鎂合金上進(jìn)行陰極電泳處理、硅烷預(yù)處理再陰極電泳處理3種不同樣件與Q235鋼螺栓連接在5％NaCl水溶液中浸泡的腐蝕規(guī)律，仔細(xì)觀察對(duì)比3種不同表面狀態(tài)的鎂合金在不同時(shí)間浸泡后的表面腐蝕情況，測(cè)定各自的腐蝕速率，對(duì)腐蝕后的區(qū)域進(jìn)行微觀分析，并用腐蝕模型對(duì)其腐蝕的行為規(guī)律進(jìn)行了解釋。結(jié)果表明：鎂合金可以通過(guò)陰極電泳處理獲得耐蝕防護(hù)涂層，硅烷預(yù)處理可以進(jìn)一步提高電泳膜層與基體的附著力，從而大大提高鎂合金與鋼螺栓接觸的耐電偶腐蝕性；AM50鎂合金與Q235鋼螺栓接觸電偶腐蝕的影響區(qū)面積不

    Abstract:

    The corrosion behavior has been studied on the three different coupled samples dipped in 5%NaCl solution. The coupled samples are Q235 steel with AM50 alloys, one without any coating, the other with cathodic E and cathodic electrophoretic coating on magnesium alloy. The surface morphologies of magnesium alloys with three different surface conditions have been observed in detail after dipped. The corrosion rates have been measured and the microstructure has been examined after ending the corrosion dip. The phenomena and law of galvanic corrosion have been explained by corrosion model. The results show that the cathodic electrophoretic coating could postpone the galvanic corrosion of magnesium alloy with steel effective and pre-silane treatment with much better protection. The affection area of galvanic corrosion did not increase with the dipping time. The corrosion developed more quickly along the coupled area than along the surface extending.
