摘要:
将前沿科学研究仪器用于实验教学可以拓宽教学实验的设计思路、提高教学实验的实施效果，激发学生对实验教学甚至是对理论教学的兴趣。首先介绍了XMU-BY&CS310系统，该系统由改装了电极平台的XMU-BY扫描电化学工作站外接一台CS310电化学工作站组装而成、拥有诱导并控制局部腐蚀发生以及观察和测量局部腐蚀原位宏观和微观电化学信号的双重功能；接着将XMU-BY&CS310系统用于实验教学设计了Q235碳钢在NaHCO3+NaCl溶液中小孔腐蚀原位电化学信号观察、测量和分析这一综合教学实验，并对实验仪器、实验准备、实验过程和结果等内容进行了详细阐述；最后总结了此综合教学实验在化学工程与工艺、材料科学与工程和安全科学与工程等专业实验教学中的应用及其所能达到的教学目标以及XMU-BY&CS310系统目前存在的不足和未来扩展的应用。
Abstract:
For experimental teaching, the application of advanced scientific research instrument can broaden its design thought and improve its implementation effect, further stimulating students’ learning interest in experimental teaching even in theoretical teaching. Firstly, a XMU-BY&CS310 system, which is assembled through modifying the electrode platform of XMU-BY scanning electrochemical workstation and connecting a CS310 electrochemical workstation externally, is introduced, and this system is able not only to induce and control the occurrence of localized corrosion but also to observe and measure the in-situ electrochemical signal of localized corrosion. Secondly, a comprehensive teaching experiment involving the observation, measurement and analysis of in-situ electrochemical signal in pitting corrosion for Q235 carbon steel in NaHCO3+NaCl solution is designed through the application of XMU-BY&CS310 system in experimental teaching, and the related contents of experimental instrument, preparation, process and result are elaborated in detail. Finally, the practical application and probable objective of this experiment in the experimental teaching of chemical engineering and technology, materials science and engineering as well as safety science and engineering is summarized, and the present deficiency and future extension of XMU-BY&CS310 system is prospected
