| 目的 分析DJB-823保护剂对典型铝合金电连接器的影响。方法 在实验室条件下针对未喷涂和喷涂DJB-823保护剂的典型铝合金电连接器开展对比酸性盐雾试验，以孔蚀率、腐蚀速率和接触电阻为指标参数，表征腐蚀行为规律。结果 保护剂对电连接器有明显的腐蚀防护作用，保护剂使得电连接器孔蚀率降低了24%~37%。保护剂能有效保证电连接器腐蚀前后接触电阻变化不大，未喷涂保护剂的电连接器盐雾腐蚀336 h后，接触电阻增大到2.5 mΩ，达到临界失效状态。结论 保护剂对酸性盐雾条件下的AF24-10型铝合金电连接器腐蚀防护作用明显。 |

| This paper aims to analyze the influence of DJB-823 protective agent on typical aluminum alloy electrical connectors. Under laboratory conditions, a acid salt spray test was carried out on the typical aluminum alloy electrical connectors with or without DJB-823 protective agent sprayed. The corrosion behavior was characterized by taking pitting factor, corrosion rate and contact resistance as index parameters. The results show that the protective agent has an obvious protective effect on electrical connectors, which reduces the pitting factor of electrical connectors by about 24%-37%; and the protective agent can effectively ensure that the contact resistance of the electrical connectors does not change much before and after the corrosion, but the contact resistance of the electrical connectors without the protective agent sprayed increases to 2.5 mΩ after 336 h of the salt spray corrosion, reaching the critical failure state. Therefore, it can be concluded that the protective agent has obvious protective effect on the AF24-10 aluminum alloy electrical connectors under the condition of acid salt spray. |
