环槽铆钉露天贮存15年结果分析

为了进一步探索环槽铆钉在航天产品上使用的可靠性，经过15年的自然环境露天贮存，研究其抗腐蚀性能和机械性能，为航天产品更广泛的使用环槽铆钉提供可靠的依据。对已用在航天产品上的环槽铆钉，经过陆地环境条件下露天贮存5年，又继续在海洋环境条件下露天贮存4年．接着又在陆地环境条件下露天贮存6年．前后共贮存15年，进行了全面系统分析，从而得出环槽铆钉在航天产品上使用是完全可靠的结论。

Result Analysis of Swage-locking Pin Which Open-air Stored after 15 years

In order to explore the reliability of swage-locking pin for using in aerospace, study corrosiveness resistance and mechanical per formance of swagelocking pin which open-air stored in natural environment after 15 years. It provides a reliable basis for using swage-locking pin in aerospace products extensively.This paper analyzes swage-locking pin which has already used in aerospace products. This kind of swage-locking pin has been open-air stored in continetal environment for 5 years and then open-air stored in occeanic environment for 4 year, at last open-air stored in continetal environment again for 6 years.From the abovementioned analysis for swange-locking pin, we get a conclusion that swage-locking pin has a good reliability in using for aerospace products.
