What should I pay attention to when using Metallographic Cold Mounting Consumables?

Metallographic cold mounting and hot compression mounting are two different processes, though they do share the same general range of applications. The most important criteria for selecting the proper mounting material are hardness, abrasion resistance, shrinkage, and chemical resistance. During the mounting process, cold-mounting compounds should exhibit low shrinkage, as the mounting material must remain hard and rigid when it solidifies. Otherwise, gaps could result in edge rounding, grinding media accumulation, and surface coatings rupture. In addition, the viscosity of the mounting material must be correct to compensate for the irregularities in the sample.

Various materials are available for this purpose. Aluminum oxide spheres have been added to castable epoxy systems to produce a higher-strength bond. Soft ceramic shot is another option, with grinding/polishing characteristics compatible with metallic specimens.

Acrylic resin and epoxy resin are common choices for mounting samples. Both types of resin have excellent adhesion to most materials. Epoxy is also suitable for vacuum impregnation, since it has a low shrinkage rate and a long curing time. While both types of mounting materials require proper care, they are safe to handle once they have been cured. These materials are also resistant to moderate heat and chemicals.
