Metallographic analysis is a widely used analytical method in the fields of materials science and mechanical engineering, used to detect the surface structure and organization of materials. Metallographic analysis can be used to determine the material, composition, organizational structure, and performance of materials, and plays an important role in the research and development, production, testing, and quality control of materials. The following are common testing items and contents for metallographic analysis.

Material composition analysis

Its main purpose is to determine the content of various elements and impurities in the material. Through metallographic analysis, the microstructure and composition distribution of the material can be clearly observed, which has important reference value for determining the composition and properties of the material.

Organizational analysis

Its main purpose is to detect the microstructure and structure of materials. Metallographic analysis can determine the performance and processing technology of materials by observing the microstructure of their surfaces. For example, metallographic analysis can be used to determine the wear and corrosion resistance of automotive engine blades.

Hardness analysis

Its main purpose is to test the hardness of the material. Hardness is an important indicator of material performance, which plays an important role in the wear resistance, corrosion resistance, and fatigue performance of materials. Through metallographic analysis, the hardness of materials can be tested to guide their research and production.

performance analysis

Its main purpose is to test the performance of the material. Metallographic analysis can be used to test the properties of materials in terms of hardness, toughness, wear resistance, corrosion resistance, etc. Through metallographic analysis of materials, the performance and application range of materials can be preliminarily determined, providing important references for material research and development and quality control.

Surface defect analysis

Its main purpose is to detect various defects on the surface of materials. Metallographic analysis can determine the processing technology and possible surface damage during use of materials by observing the defects and damages on their surfaces.

The above are the common testing items and contents of metallographic analysis. Metallographic analysis, as an important material analysis method, can not only be used for research and production, but also for quality control and performance testing, playing an important role in ensuring product quality and improving performance.
