为验证某皮卡车型的防腐蚀性能,对该车进行了60个循环的整车强化腐蚀试验,分析了镀锌板、结构设计、打胶工艺对车身防腐蚀性能的影响。结果表明,镀锌板的防腐蚀性能明显优于非镀锌板,相同厚度的热镀锌板和电镀锌板的防腐蚀性能相当;A 柱与翼子板间夹缝宽度小于0.1 mm 时,容易产生腐蚀,而当夹缝宽度大于0.2 mm时,则可以避免锈蚀现象;在钢板搭接位置适量涂覆焊缝密封胶,可保证6个腐蚀年(60个循环试验)不会出现腐蚀问题。本工作对各种腐蚀模态作了试验及理论的探索。
為驗證某皮卡車型的防腐蝕性能,對該車進行瞭60箇循環的整車彊化腐蝕試驗,分析瞭鍍鋅闆、結構設計、打膠工藝對車身防腐蝕性能的影響。結果錶明,鍍鋅闆的防腐蝕性能明顯優于非鍍鋅闆,相同厚度的熱鍍鋅闆和電鍍鋅闆的防腐蝕性能相噹;A 柱與翼子闆間夾縫寬度小于0.1 mm 時,容易產生腐蝕,而噹夾縫寬度大于0.2 mm時,則可以避免鏽蝕現象;在鋼闆搭接位置適量塗覆銲縫密封膠,可保證6箇腐蝕年(60箇循環試驗)不會齣現腐蝕問題。本工作對各種腐蝕模態作瞭試驗及理論的探索。

A 60-cycle vehicle accelerated corrosion test was performed to verify the corrosion performance of a pickup.And the effects of different body structures,glue process and galvanized sheet on the corrosion resistance were investigated.The results showed that corrosion resistance of galvanized sheet was better than that of non galvanized sheet,and there was no difference between hot dip galvanized sheet and galvanized sheet when the thickness was the same.Corrosion was more likely to occur when the gap between A-pillar and front wing was smaller than 0.1 mm,but corrosion could be avoided when the gap was larger than 0.2 mm.Appropriate amount of PVC sealant must be applied to welding seams to ensure sufficient corrosion resistance for 6 corrosion test years (60-cycle test).All the above corrosion modes were experimentally studied and theoretically explored in this research.
