- 研究了一种光纤上电沉积制备 Fe-C 合金的工艺：首先对光纤粗化处理，通过化学镀制备金属薄膜中间层，再电镀 Fe-C 合金。采用电化学工作站考察添加剂对腐蚀电位的影响，利用 SEM 和 EDS 对镀层微观形貌和元素组成进行分析。通过单因素实验和正交试验对工艺参数进行筛选优化，结合赫尔槽实验对试片进行分析，确定了电镀工艺参数为：十二烷基硫酸钠 0.20 g/L 、糖精钠 1.0~1.5 g/L 、柠檬酸 2.0 g/L 、抗坏血酸 7.0 g/L 、温度 30 ℃ 、 pH 为 3.0 、阴极电流密度 0.3~1.0 A/dm 2 。采用电镀 Fe-C 合金工艺制备的镀层在成分和腐蚀规律上与碳钢类似，可以用来制备腐蚀传感器。
- Abstract:
- ： A technique for preparing Fe-C alloy by optical fiber electrodeposition was studied. First ， the optical fiber was coarsened ， the intermediate layer of metal film was prepared by electroless plating ， and then the Fe-C alloy was electroplated. Electrochemical workstation was used to test the influence of additives on the corrosion potential ， SEM was used to observe the microstructure of the coating ， and EDS was used to analyze the element composition of the coating. Single factor experiment and orthogonal experiment were used to optimize the process parameters ， and the samples were analyzed by Hull cell experiment. The plating process parameters were determined as follows ： sodium dodecyl sulfate 0.20 g/L ， sodium saccharin 1.0-1.5 g/L ， citric acid 2.0 g/L ， ascorbic acid 7.0 g/L ， temperature 30 ℃ ， pH 3.0 ， cathode current density 0.3-1.0 A/dm 2 . The results showed that the coatings prepared by electroplating Fe-C alloy were similar to carbon steel in composition and corrosion regulation ， and can be used to fabricate corrosion sensors.
