- 本文以车用镀锌钢为研究对象，对比研究了其在大气腐蚀环境、中性盐雾腐蚀、循环腐蚀盐雾条件下的腐蚀行为。采用电化学、微观表征和失重法等分析手段多维度探讨了镀锌钢在三种典型腐蚀条件下的腐蚀规律。提出了镀锌材料腐蚀拟合矩阵，量化分析了不同腐蚀环境条件下的材料腐蚀特征，为探索汽车评估方法缩短腐蚀试验周期、加快腐蚀验证进度提供借鉴。
- Abstract:
- In this paper, the corrosion behavior of galvanized automobile steel under atmospheric corrosion, neutral salt spray corrosion and cyclic corrosion salt spray conditions was studied. The analysis methods such as electrochemistry, microscopic characterization and weight loss method are used. The corrosion behavior of anticorrosive material under three typical corrosion conditions are discussed in multiple dimensions. As a result, a corrosion fitting matrix of galvanized materials was proposed, and the corrosion characteristics of materials under different corrosive environmental conditions were quantitatively analyzed, which provided a reference for exploring automobile evaluation methods to shorten the corrosion test cycle and speed up the progress of corrosion verification.
