What is Metallographic Inspection
Jul 19,2024
Metallographic inspection is a reflection and characterization of the track shoes material composition, non-metallic inclusions, and even the quantity, morphology, size, distribution, orientation, and spatial arrangement state.
The main purpose of metallographic inspection: on the one hand, it is a routine inspection, judging or determining the quality and production process of the track plate based on existing knowledge. If there are defects, the cause of the defects can be found. On the other hand, it is to have a deeper understanding of the intrinsic relationship between the track shoe structure and various properties, as well as the laws of the formation of various structures, etc., to provide a reliable basis for the development of new materials and new processes.
The metallographic inspection process of the track shoe generally includes the following steps:
1. Sample preparation:
· Cutting: No matter what method is used to cut the track pad sample, it should be noted that the sample should not change its structure due to deformation or heating. For samples cut at high temperature, the heat-affected part must be removed.
· Grinding: After cutting, the metallographic sample needs to be ground to obtain a bright grinding surface. Many samples are difficult to grind directly and need to be inlaid.
·Polishing: Due to the large difference in hardness of each component or the significant difference in color of each phase itself, the structure can be distinguished under a microscope in the polished state. The purpose of polishing is to remove the fine wear marks and surface deformation layer left by fine grinding on the metallographic grinding surface, so that the grinding surface becomes a smooth mirror without scratches.
2. Corrosion treatment:Place the sample in a corrosive agent to remove the surface oxide layer and other impurities to reveal the internal structure of the metal.
3. Cleaning and drying: Wash the sample and dry it with solvents such as ethanol or chloroform.
4. Microscopic observation: Use a metallographic microscope to observe the metallographic structure of the sample and take photos to record it.
5. Image analysis: Use software to analyze the microphotographs and measure parameters such as grain size and phase area ratio.
6. Result analysis: Based on the observation and analysis results, describe and explain the metallographic structure and properties of the sample.
7. Experimental report: Summarize the experimental process, results and analysis into a report, including sample identification, treatment methods, observation results and conclusions.
These steps require strict control of experimental conditions and operating techniques to ensure accurate and reliable metallographic analysis results.
