Ideological and Political Case Design of Experiment of Corrosion and Protection Linking with National Major Projects
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.
