What are the characteristics of the inlay materials used in metallographic inlay machines?

The commonly used mounting materials for metallographic mounting machines mainly include metallographic mounting powder and acrylic, each with unique characteristics.
Metallographic mounting powder is a thermosetting resin that is in powder form when not heated, making it easy to store and operate. When placed in a metallographic mounting machine and heated to a certain temperature, it can quickly solidify and form. The cured resin has high hardness, good wear resistance, and corrosion resistance, providing stable support and protection for the sample to prevent damage during subsequent sample preparation and analysis processes. Moreover, its shrinkage rate is small, allowing it to maintain good dimensional stability during the cooling process and bond tightly with the sample without easily falling off.
Acrylic belongs to thermoplastic resins; it softens at high temperatures and has good fluidity and plasticity, enabling it to wrap the sample evenly so that the sample presents a transparent effect in the mounting block, facilitating direct observation of the sample morphology. After cooling, acrylic becomes hard and has a certain strength. However, using acrylic has higher requirements for the functionality of the mounting equipment, requiring the device to precisely control temperature and pressure to satisfy the softening and hardening processes.
