Metallographic testing is an important means of material analysis. Simply said that metallographic analysis is to select one of the analysis surfaces on the target material for microscopic observation. The observation surface can be a surface that has not been corroded, used to observe material features such as inclusions, holes, and cracks; it can also be a surface after corrosion, using the different reaction rates of various tissues to the corrosive liquid to show surface shape of varying depths, thereby reversely explaining the types and distribution patterns of various tissues.

Metallography is a systematic discipline that requires a lot of basic knowledge of materials science as a basis, combined with the understanding of process characteristics, relying on skilled sample preparation techniques and rich analysis experience, in order to reveal the mechanism hidden behind the metallographic photographs, draw accurate conclusions, and guide the process.

Although metallographic analysis depends on experience to a certain extent, reliable sample preparation is the premise of analysis. Perfect sample preparation first requires reliable sample preparation equipment.

According to the basic steps of sample preparation, metallographic equipment can be roughly divided into the following three categories:

Cutting equipment: Cut the original sample to obtain the most representative target analysis surface.

Inlay equipment: Place the cut sample into the mounting resin to form a standard sample for subsequent grinding and polishing.

Grinding and polishing equipment: Flatten the target analysis surface to eliminate scratches for later microscopic observation.

There are various subcategories in each major category of cutting, inlaying and grinding and polishing. Different models of equipment are aimed at different material characteristics and application requirements. The more expensive the better. Adding hundreds of metallographic consumables, it is even more dazzling. How to choose the most suitable equipment configuration and consumables solution for yourself requires consulting experienced metallographic experts.
