在碳素材料的理化检验中,研究碳素材料的显微结构的特征具有重要的意义。本文介绍部分碳素材料在灵敏色调(色干涉)下的显微结构的彩色照片,并以此来说明它们的结构特征。试验条件:应用大型卧式金相显微镜(Neophoto),光源采用碳棒弧光源,经紫外滤光器,并用RI灵敏色片产生灵敏色调照明,采用国产GB—17°彩色胶卷摄照,彩色正片采用放大印制法。试样制备接一般金相试样的要求,经磨制、粗抛和精抛光而成,对于粉状、粒状及结构
In the physical and chemical testing of carbon materials, the study of the microstructure of carbon materials is of great significance. This article presents a color photograph of the microstructure of some carbon materials under a sensitive color tone (color interference) and illustrates their structural features. Test conditions: Large horizontal metallographic microscope (Neophoto), the light source using carbon rod arc light source, the UV filter, and use RI sensitive color sensitive color to produce lighting, using domestic GB-17 ° color film camera, color positive Using enlarged printing method. Sample preparation followed by the general metallographic sample requirements, after grinding, rough throwing and fine polishing, for the powder, granular and structure
