- 摘要:
- 通过共沉积将纳米Al2O3颗粒掺杂于锡镀层中，在紫铜表面制备出锡基复合镀层。测试了锡基复合镀层的极化曲线和电化学阻抗谱，并与紫铜和锡镀层作比较，结果表明：锡镀层和锡基复合镀层相对于紫铜都为阳极性镀层，且都是以自身优先被腐蚀的方式对紫铜起到双重保护作用，但是两种镀层对紫铜的保护作用存在一定的差异。与锡镀层相比，锡基复合镀层的腐蚀电位正移了44 mV，腐蚀电流密度也有所降低，容抗弧半径和电荷转移电阻较大，双电层电容较小。锡基复合镀层较锡镀层对腐蚀过程中电子转移具有较强的阻碍作用，能为紫铜提供较好的保护作用。
- Abstract:
- Tin-based composite coating doped with nano-Al2O3 particles on the surface of red copper was prepared by codeposition. The polarization curve and electrochemical impedance spectrum of tin-based composite coating were tested and compared with those of red copper and tin coating. The results showed that tin coating and tin-based composite coating were both anodic coating relative to red copper, and both of them can provide dual protection to red copper in the form of self-priority corrosion. However, there was some difference in the protection effect between these two coatings. Compared with tin coating, the corrosion potential of tin-based composite coating was positively shifted by 44 mV, and the corrosion current density was also decreased. The capacitive reactance radius and charge transfer resistance were larger, and the double layer capacitance was smaller. Tin-based composite coating has stronger resistance to electron transfer than tin coating, and it can provide better protection effect to red copper.
