摘要:
采用化学镀方法在钕铁硼表面制备 Ni - Mo - P/PTFE 复合镀层，并运用正交实验法考察 PTFE 乳液浓度、镀液温度、化学镀时间和搅拌速率对 Ni - Mo - P/PTFE 复合镀层腐蚀速率的影响。结果表明： Ni - Mo - P/PTFE 复合镀层的腐蚀速率随着镀液温度升高、 PTFE 乳液浓度增加和搅拌速率提高都呈先减小后增大的趋势，而随着化学镀时间延长呈持续减小趋势。最优工艺参数为：镀液温度 90 ℃ 、 PTFE 乳液浓度 10 mL/L 、化学镀时间 110 min 、搅拌速度 180 r/min ，镀液温度对 Ni - Mo - P/PTFE 复合镀层的腐蚀速率影响程度最大。采用最优工艺参数制备的 Ni - Mo - P/PTFE 复合镀层腐蚀速率更低，约为 3.75 mg·cm -2 ·h -1 ，容抗弧半径增大且在 10 -2 Hz 处的阻抗值由 8500 Ω ·cm 2 增大到 10500 Ω ·cm 2 左右，其耐蚀性明显好于非最优工艺参数制备的 Ni - Mo - P/PTFE 复合镀层。
Abstract:
： Ni - Mo - P/PTFE composite coating was prepared on the surface of NdFeB by electroless plating ， and the influence of PTFE emulsion concentration ， bath temperature ， electroless plating time and stirring rate on the corrosion rate of Ni - Mo - P/PTFE composite coating was investigated by orthogonal experiment. The results showed that the corrosion rate of Ni - Mo - P/PTFE composite coating decreased first and then increased with the rise of bath temperature ， the increase of PTFE emulsion concentration and stirring rate ， while it show a continuous decreasing trend with the extension of electroless plating time. The optimal process parameters were as follows ： bath temperature 90 ℃ ， PTFE emulsion concentration 10 mL/L ， electroless plating time 110 min ， stirring rate 180 r/min ， and the influence degree of bath temperature on the corrosion rate of Ni - Mo - P/PTFE composite coating was the greatest. The corrosion rate of the Ni - Mo - P/PTFE composite coating prepared by optimal process parameters was lower ， which was about 3.75 mg·cm -2 ·h -1 . The arc radius of capacitive reactance was increased and the impedance value at 10 -2 Hz increased from 8500 Ω ·cm 2 to about 10500 Ω ·cm 2 ， indicating that the corrosion resistance of the Ni - Mo - P/PTFE composite coating prepared by optimal process parameters was better than that of the Ni - Mo - P/PTFE composite coating prepared with non-optimal process parameters.
