将腐蚀与防护实验和国家重大工程衔接的课程思政案例设计
摘要:
将胶州湾跨海大桥材料的腐蚀防护研究作为实际应用案例引入物理化学实验教学。通过结合工程实际改进实验，增加了相关材料在不同腐蚀介质中的腐蚀行为研究等内容，对相关材料及几类防护措施的防护效果进行了比较研究。实验将原物理化学实验中涉及的线性扫描伏安(极化曲线测量)和电化学阻抗方法进行了组合，对Q235和Q275两种合金钢、锌合金和镁合金两种牺牲阳极材料、无涂层和有环氧涂层的钢铁在模拟海水和真实海水两种电解质溶液环境中的腐蚀性能和防护效果进行了研究。改进后的实验可以增强学生学以致用的意识，增强他们对工程问题的综合性和复杂性的认识，还可以培养团队意识和合作能力，通过培养腐蚀防护意识和绿色环保意识强化学生的学科素养和社会责任感。

Ideological and Political Case Design of Experiment of Corrosion and Protection Linking with National Major Projects
Abstract:
The study on corrosion protection of Jiaozhou Bay Bridge material is introduced into physical chemistry experiment as a practical application case. By combining with the engineering practice to improve the experiment, the content of related materials and corrosion behavior in different corrosive media is added, and the protective effect of related materials and several kinds of protective measures is compared. Linear sweep voltammetry (Tafel polarization curve measurement) and electrochemical impedance spectroscopy are used in the experiment. The corrosion properties and protection effects of Q235 and Q275 steel, zinc alloy and magnesium alloy sacrificial anode materials, uncoated and epoxy-coated steel sample in simulated seawater and real seawater electrolyte solutions are studied. The improved experiment can enhance students’ awareness of applying what they have learned in real applications, enhance their understanding of the comprehensiveness and complexity of engineering problems, cultivate team spirit and cooperation ability, and strengthen students’ disciplinary literacy and social responsibility by cultivating their awareness of corrosion protection and green environmental protection.
