Abstract: The design of anti-corrosion reliability and durability targets for automotive body aims to ensure that the body can effectively resist corrosion in various complex environments and operating conditions, and maintain product performance to meet customer needs within the predetermined service life. Setting too high anti-corrosion targets can increase the cost of body anti-corrosion, thereby affecting enterprise profits; while setting too low targets may lead to customer dissatisfaction and damage product reputation. Therefore, it is crucial to set anti-corrosion reliability and durability targets reasonably. This study introduces quality function deployment (QFD), reliability and durability research methods to deeply explore the key elements, research objects and methods of anti-corrosion target setting. Practice cases is proved that based on the improved corrosion target setting method, can develop "just right" anti-corrosion reliability and durability targets that not only meet customer needs but also avoid over design, so as to control costs while ensuring product quality.
