LY12铝合金微弧氧化黑色陶瓷膜结构及耐腐蚀性研究 姚忠平1,姜兆华1,吴振东1,张雪林1,王志江1 (1.哈尔滨工业大学,黑龙江,哈尔滨,150001;2.白城师范学院,吉林,白城,137000) 摘要:在多聚磷酸钠和含铬添加剂组成的电解液体系中,采用微弧氧化方法对LY12铝合金表面制备颜色均匀的黑色陶瓷膜.利用扫描电镜,X射线衍射仪和电化学分析仪研究了陶瓷膜结构,形貌和耐蚀性.陶瓷膜厚度随着反应时间的延长近似性线增加,添加剂具有增加陶瓷膜厚度的作用.膜层表面残留大量没有完全封闭的放电通道:沿陶瓷膜截面由内至外,黑色陶瓷膜的颜色逐渐变深,铬的含量增加,铝,铜的含量减少.含添加剂陶瓷膜由大量的α-Al2O3及少量的γ-Al2O3组成;不含添加剂陶瓷膜由γ-Al2O3组成,乳白色.陶瓷膜层试样的耐腐蚀性能要好于基体,含铬的黑色陶瓷膜耐腐蚀性能大幅度提高.
