- 摘要:
- 以电化学沉积在“再制造”领域的应用为背景，设计了稀土Ce对Ni-Co合金镀层微观组织与性能的影响综合电化学实验。以电化学沉积理论为指导，以学生掌握Ni-Co镀层的制备、表征与性能测试方法为目的，以硫酸镍体系为主要原料，制备了Ni-Co合金镀层。利用扫描电子显微镜与能谱分析仪对镀层的微观组织和化学成分进行了表征，利用X射线衍射仪对镀层的相结构进行了分析，利用显微硬度计、摩擦磨损试验机与电化学工作站对镀层的显微硬度、耐磨性与耐蚀性进行了测试。本实验可以提升学生的基本实验技能，同时，实验涉及电化学、材料、机械等多学科交叉融合，在教学实施过程中可以提高学生的创新能力与科研素养。
- Abstract:
- The comprehensive electrochemical experiment of the effect of rare earth Ce on the microstructure and properties of Ni-Co alloy coatings was designed based on the application of electrochemical deposition in the field of “remanufacturing”. Ni-Co alloy coating was prepared with nickel sulfate system as the main raw material for the purpose of students mastering the preparation, characterization and property testing methods of Ni-Co coating under the guidance of electrochemical deposition theory. The microstructure and chemical composition of the coating were characterized by scanning electron microscope and energy dispersive X-ray spectroscopy. The phase structure of the coating was analyzed by X-ray diffraction. The microhardness, wear resistance and corrosion resistance of the coating were tested by microhardness tester, friction and wear testing machine and electrochemical workstation. This experiment could improve students’ basic experimental skills. Meanwhile, the experiment combined multiple subjects of electrochemistry, materials, machinery, which improve students’ innovative ability and scientific research literacy in the process of teaching practice.
