| Abstract: |
| 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. |
