| 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. |
