| 目的 对比分析不同试验环境下微动开关的腐蚀行为，研究其腐蚀机理。方法 针对干湿交替酸性盐雾试验环境、盐雾/SO2复合试验环境及热带海洋大气环境下微动开关接触电阻的变化趋势，以及对不同试验环境后微动开关内部被腐蚀的细小结构件进行微观形貌观察和能谱分析。通过对比分析不同试验环境下微动开关的腐蚀机理及其对电性能参数的影响。结果 含硫环境对微动开关内部银质触点的影响最严重。结论 腐蚀产物硫化银的导电性极差，这会导致微动开关接触电阻升高。 |

| Objective To compare and analyze corrosion behaviors of microswitch under different test conditions and study on its corrosion mechanism. Methods In this paper, contact resistance as well as external and internal structure corrosion situations of microswitch under alternate environment with wetting and drying acidic salt spray, composite test environment of salt spray/SO2 and atmosphere environment of tropical ocean were observed and analyzed with energy spectrum. Moreover, corrosion mechanisms and their effect on electrical property parameters under different environment were analyzed and discussed. Results The environment with sulphur affected silver contactors in microswitch the most. Conclusion The product of this process is silver sulfide which has extremely poor electrical conductivity. As a result, contact resistance of the microswitch becomes stronger. |
