摘要
采用扫描式微弧氧化(SMAO)技术在A356铝合金制备了陶瓷涂层。测定了反应过程中涂层的电压-时间、动力学生长曲线,研究了涂层的显微组织、成分分布,分析涂层的相组成及显微硬度分布,并比较了氧化前后极化曲线的变化。结果表明,在硅酸盐溶液中获得的涂层主要由α-Al_2O_3、γ-Al_2O_3和莫来石组成,涂层与基体呈现良好的冶金结合。与A356传统式微弧氧化(CMAO)涂层相比,SMAO涂层中α-Al_2O_3含量略多、孔隙率更低,显微硬度更高。此外,两种氧化处理之后,铝合金的耐腐蚀能力均得到显著提高。
A356 aluminium alloy was treated by scanning micro arc oxidation(SMAO) method.The voltage-time and coating thickness-time curves were record.The microstructure and composition of coatings were analyzed,and the phase constituent and microhardness profile were measured.The corrosion behavior of the composite was evaluated by polarization test.Results show that the coating deposited in silicate electrolyte consists of a-Al_2O_3,y-Al_2O_3 and mullite.The coating and the substrate presented excellent metallurgical bonding.Compared wife CMAO on A356 alloy,SMAO coating wife more α-Al_2O_3 phase,less porous and higher micro hardness.After both of CMAO and SMAO treatment,the corrosion resistance of A356 alloy was significantly improved.
