引言目前,用金相显微镜在机件上直接拍摄金相组织,存在着不少的困难。例如形状复杂的机件,显微镜无法平稳放置,在车间,受到机械振动的影响,使聚焦发生困难等,而不能得到满意的效果。使用金相复制膜方法,所得到的复制膜可以代替直接拍摄的金相组织,以备复查。 Introduction At present, the use of metallographic microscope directly on the mechanical filming of metallographic structure, there are many difficulties. For example, the shape of complex parts, the microscope can not be placed in a smooth, mechanical vibration in the workshop, so focus difficulties, etc., and can not be satisfied with the results. The use of metallographic copy film method, the resulting copy film can replace the direct filming of the microstructure to prepare for review.
