Description

technical field

[0001] The invention belongs to the field of metal material science, specifically belongs to the field of metal material grinding and polishing processing technology, is an auxiliary facility for striving for grinding and polishing precision and flatness in the grinding and polishing process, and belongs to the supplementary design of traditional grinding and polishing equipment. technical background

[0002] Metallographic analysis is one of the important means of experimental research on metal materials. Quantitative metallographic principles are used to determine the three-dimensional spatial morphology of the alloy structure by measuring and calculating the metallographic microstructure of the two-dimensional metallographic sample grinding surface or thin film, so as to establish Quantitative relationship between alloy composition, structure and properties. Applying the image processing system to metallographic analysis has the advantages of high precisio...
