摘　　要：在20℃下,采用氟化铵-乙二醇电解液对FeCrAl不锈钢进行阳极氧化以制备纳米多孔结构,研究了氧化电压、氧化时间对氧化膜多孔结构的影响,并对操作参数进行了优化。然后将氧化铝凝胶涂覆于优化制得FeCrAl的样品表面,并通过高频超声验证涂层强度。研究表明,最佳阳极氧化条件为10 min,50 V。阳极氧化法处理后的涂层牢固度优于高温预处理法。FeCrAl stainless steel was anodized in ammonium fluoride-glycol electrolyte at 20℃to prepare a nano-porous structure.The influences of oxidation voltage and time on the porous structure of oxide film were studied,and the operating parameters were optimized.Aluminum oxide gel was coated on the surface of pretreated FeCrAl samples,and the coating strength was tested by high-frequency ultrasonic.It was concluded that the optimum anodic oxidation condition was 10 min and 50 V,and the coating mechanical strength over FeCrAl pretreated via anodic oxidation is better than that of high-temperature pretreatment.
