摘要(Abstract)：

利用微弧氧化技术,通过在硅酸盐电解液中加入石墨烯添加剂,在LY12铝合金表面制备一层含碳陶瓷层,采用扫描电镜、X射线衍射仪和电化学工作站等对陶瓷层的微观结构、成分组成以及耐磨耐蚀性能进行分析检测。结果表明:制备的含碳陶瓷层表面微孔尺寸和粗糙度值均明显降低,主要由Al_2O_3、SiO_2以及Al_2SiO_5物相组成。相比于不含碳的陶瓷层,含碳陶瓷层最大厚度为20.5μm,而且更加均匀致密。在相同的摩擦条件下,含碳陶瓷层的摩擦系数仅为0.09,比不含碳陶瓷层摩擦系数值降低了近3倍,表现出良好的减摩性能。由于含碳陶瓷层的厚度和致密性提高,使其腐蚀电流密度显著降低,耐蚀性也得到了明显的改善。
