测试与材料腐蚀相关的工艺通常会很困难, 尤其是在非水环境中。在这里, 我们提出了短期和长期测试非水环境 (如生物燃料, 尤其是含有生物乙醇的环境) 腐蚀行为的不同方法。

这些方法有助于回答有关金属材料的耐腐蚀性、不同环境的耐腐蚀性以及不同环境下防腐剂效率的问题。这些方法的主要优点是,它们可以同时应用于水性和非水性环境。该方法在汽车和燃料工业中可用于研究乙醇汽油混合物对燃料系统内不同建筑材料的腐蚀作用。

展示这个程序的将是卢卡斯·马特约夫斯基,我团队的成员。要测试金属液体系统的静态浸入腐蚀,首先在装有用于悬挂分析样品的挂钩的 250 毫升瓶中加入 100 到 150 毫升的液体腐蚀环境,并使用 1,200 网眼砂纸在自来水下研磨和抛光金属样品的表面,以实现表面的均匀调整。接下来,用约25毫升丙酮和约25毫升乙醇彻底脱脂样品表面。
