| 目的：对新研发的多因素综合海洋气候环境自然加速试验技术相对热带海洋气候环境户外暴露试验的相关性和加速性进行验证。方法：分别采用多因素综合海洋气候环境自然加速试验装置和对应的试验方法企业标准，以及传统的户外暴露试验方法，以不同表面处理工艺的汽车紧固件、标准金属、有机涂层和塑料为样品进行验证试验，采用Spearman秩相关系数法和加速因子（AF）法对相关性和加速性进行进一步验证。结果：紧固件、标准金属和有机涂层在多因素综合海洋气候环境自然加速试验和海洋气候环境户外暴露试验过程中，都表现出相同的腐蚀失效模式；多因素综合海洋气候环境自然加速试验相对远海场(离海岸线350米)户外暴露试验紧固件秩相关系数为1，标准金属秩相关系数为0.8；多因素综合海洋气候环境自然加速试验相对海洋平台户外暴露试验标准金属秩相关系数为1。多因素综合海洋气候环境自然加速试验相对于远海场户外暴露试验，镀锌镍合金紧固件、无铬锌铝涂层紧固件、拉弗莱紧固件和石墨烯紧固件的加速倍率分别为7.7、11.3、10.3和13.5倍；Q235、工业纯铝、工业纯锌和工业纯铜的加速倍率分别为11.8、11.5、9.3和3.7。多因素综合海洋气候环境自然加速试验相对于海洋平台户外暴露试验，Q235、工业纯铝、工业纯锌和工业纯铜的加速倍率分别为3.4、2.1、4.5和2.2倍。 结论：多因素综合海洋气候环境自然加速试验相对海洋气候环境户外暴露试验具有良好的相关性，而且对海洋平台的相关性更好。对于紧固件表面处理工艺、标准金属和有机涂层而言，多因素综合海洋气候环境自然加速试验相对海洋气候环境户外暴露试验具有高的加速倍率。 |

| Purpose: Verification of the relativity and acceleration of multi-factors integrated marine climate natural accelerated test technologies to outdoor exposure test in tropic marine climate. Methods: using multi-factors integrated marine climate natural accelerated test device and the relative enterprise standard as well as traditional marine climate outdoor exposure, using automobile fasteners of different surface treatment technologies, standard metals, organic coatings, and plastics as specimen, and using Spearman order relativity coefficient method and acceleration factor method to further verify the relativity and acceleration. Result: automobile fasteners, standard metals and organic coatings indicated that their corrosion failure modes are the same in multi-factors integrated marine climate natural accelerated test and tropic marine climate outdoor exposure test; order relativity coefficient of fasteners and standard metals are 1 and 0.8 respectively for the accelerated test to outdoor exposure test in the exposure site 350 meters from South China Sea; order relativity coefficient of standard metals is 1 for the accelerated test to outdoor exposure test in the marine platform; for the accelerated test to outdoor exposure test in exposure site, the acceleration rate of zinc nickel alloy plated , chromium free zinc aluminum alloy coated, LAFＲE coated and Graphene coated fasteners are 7.7, 11.3, 10.3 and 13.5 respectively and that of Q235, industrial pure Aluminum, industrial pure Zinc, and industrial pure Copper are 11.8,11.5,9.3 and 3.7 respectively; for the accelerated test to outdoor exposure test in the marine platform, the acceleration rate of Q235, industrial pure Aluminum, industrial pure Zinc, and industrial pure Copper are 3.4, 2.1, 4.5 and 2.2 respectively. Conclusion: multi-factors integrated marine climate natural accelerated test technology has good relativity to tropic marine climate outdoor exposure, and better to marine platform exposure. The technology also has high acceleration rate to traditional marine climate outdoor exposure for surface treatment technologies of automobile fasteners, standard metals and organic coating. |
