Effect of annealing temperatures on microstructure and properties of magnesium alloy anode sheet

对镁合金热轧板材在不同温度进行退火处理,采用恒电流扫描法、动电位极化扫描法和浸泡法研究不同退火温度对其在3.5％(质量分数)NaCl中的电化学性能和自腐蚀性能的影响；采用光学显微镜、扫描电镜和X射线衍射仪对其显微组织和腐蚀形貌进行观察.结果表明:镁合金阳极板材在退火过程中发生静态再结晶,经250℃、300℃退火1h,合金板材发生完全再结晶；经300℃退火1h后,镁合金阳极板材的电化学活性最好,放电稳定电位达-1.654 V(vs SCE),但其耐蚀性能最差,腐蚀电流密度为180.38 μA/cm2.
