优良的金相照片要求清晰醒目、层次分明、色调适中,金相组织中的各组成相都要如实地记录下来。有的须突出重点,分出主次。影响照片质量的因素很多,如试样制备,显微镜光学系统的调整,镜头的选择与组合,光栏的合理使用,底片曝光显影,印相时相纸的选择,曝光显影等一系列环节不得有丝毫疏忽,如果有一个环节不正确,就得不到优良的金相照片。一、试样照相用的试样,尤其是拍照视场,一定要平整,无划痕,无麻点,无水迹,无污、
Fine metallographic photo requirements clear and eye-catching, structured, moderate color, the microstructure of the various phases must be truthfully recorded. Some must highlight the main points. Affect the quality of the photo a lot of factors, such as sample preparation, microscope optical system adjustment, the choice and combination of the lens, the rational use of the light bar, film exposure and development, photographic paper selection, exposure and development of a series of links may not have The slightest negligence, if there is a link is not correct, you can not get good metallographic photos.
