Metallographic analysis and corrosion test
Metallographic analysis is one of the important means of experimental research on metalmaterials. Quantitative metallographic principles are used to determine the three-dimensionalspatial morphology of the alloy structure by measuring and calculating the metallographicmicrostructure of the two-dimensional metallographic sample grinding surface or thin film, soas to establish quantitative relationship between alloy composition, structure and properties.Applying the image processing system to metallographic analysis has the advantages of higrprecision and efficiency, which can greatly improve work efficiency.Computer auantitative metalloaraphic analvsis is aradually becoming a powerful tool for peopleto analyze and study various materials, establish the auantitative relationshin between themicrostructure of materials and various properties, and study the transformation kinetics otmaterials.The computer image analysiscan easily measure the area percentage,systemaveraae size, averade spacina, aspect ratio and other parameters of the features, and thensize and distribution of the features accordingdetermine the three-dimenslona shape. auantity.to these parameters.relationship with the mechanical propertiesIt also establshes anintrinSlCof materials, providing reliable data for more scientific evaluation of materials and rational use otmaterials.During the operation of the equipment, the use of corrosion inhibitors can slow down thecorrosion of the equipment, but whether the corrosive agent is suitable for the equipment itselneeds to be known through experiments. According to the experimental results, engineers canadlust the tvpe or proportion ot the corrosive agent, tind out the problem in time, therefore toprevent malor accidents. Meanwhile engineers can master the corrosion rate of the equlpmentduring operation, preset the service life of the equipment, the whole system can be moreeconomicaland safer
