摘　　要：材料类专业开放实验可以将实践操作与所学的理论知识联系,强调学生的主导作用,充分调动他们的学习积极性。电弧等离子体干法除鳞的开放实验,通过改变实验参数研究电弧除鳞速率的变化;通过SEM、XRD对除鳞前后样品表面形貌及物相的表征,对电弧除鳞的效果进行评价。设计实验以及对结果的分析培养了学生的科学思维和独立思考的能力。在具体的实验操作中,学生的动手能力也得到充分的锻炼。The open experiment of materials major can combine practice and theory and stress undergraduates’leading role,which can fully arouse their enthusiasm for learning.In this arc descaling experiment,the relation between descaling rate and experimental parameters was studied.SEM and X RD were employed to study morphologies and compositions of the sample surface before and after arc descaling,which were used to evaluate the effects of arc descaling.Scientific thought and ability of independent thinking were developed through the experimental design and the results analysis.Students’practical ability was improved as well via experimental operation.
