AbolishedCorrosion of metals and alloys-Determination of bimetallic Corrosion in outdoor exposure corrosion tests
金属和合金的腐蚀 双金属室外暴露腐蚀试验
Application Summary AI generated
This standard specifies the test method for evaluating galvanic corrosion between dissimilar metals when exposed to outdoor atmospheric conditions. It is applied in materials selection and product design for industries such as construction, automotive, and marine engineering, where bimetallic joints must withstand natural weathering. The standard guides engineers in predicting corrosion risks and ensuring long-term durability of assemblies like bolted structures, heat exchangers, or outdoor electrical enclosures.
