- 摘要:
- 将超声波与化学镀锡工艺相结合，研究了镀液温度对超声镀锡层微观形貌、表面成分和耐腐蚀性能的影响。结果表明：超声波化学镀锡的沉积速度较常规化学镀锡提高了近30 %，获得的超声镀锡层表面比较平整致密，表现出良好的耐腐蚀性能。随着镀液温度升高，超声镀锡层的耐腐蚀性能先增强后减弱，与表面状况发生明显变化有关。超声镀锡层成分未随着镀液温度升高而发生明显改变。镀液温度为80 ℃时获得的超声镀锡层表面平整性和致密性最佳，具有相对较好的耐腐蚀性能。
- Abstract:
- Ultrasonic-assisted electroless tin plating was carried out, and the effect of bath temperature on the microstructure, surface composition and corrosion resistance of ultrasonic tin coating was studied. It was found that the deposition rate of ultrasonic-assisted electroless tin plating was nearly 30 % higher than that of conventional chemical tin plating, and the surface of ultrasonic tin coating was relatively flat and compact, showing good corrosion resistance.. The results showed that the corrosion resistance of ultrasonic tin coating was first strengthened and then weakened with the rise of bath temperature, which was relative to obviously change of the surface condition of ultrasonic tin coating. However, the composition of ultrasonic tin coating was not changed obviously with the rise of bath temperature. The ultrasonic coating obtained at 80 ℃ presented a smooth and compact surface, and exhibited excellent corrosion resistance.
