Using epoxy to mount a sample before processing is an effective way to provide additional support to samples during subsequent grinding and polishing and is especially important with delicate and porous samples.
Embedding specimens in mounting media prior to preparation offers many advantages. Mounting not only offers protection for both user and specimen, but also facilitates automation – to name only a few. However, errors may occur during mounting – e.g. the specimen may be mounted upside down or at an angle. How do you get out […]
Mounting presses are an excellent way to mount many specimens, and can be the most efficient and economical choice for many samples. However, the heat and pressure can cause significant damage to many samples – especially soft, porous or friable materials and coatings. In these cases, castable mounting systems must be used. Castable epoxy systems […]
Medical implants are increasingly used today, stemming from newer alloy developments and manufacturing techniques, such as additive manufacturing, necessitating a closer outlook at their microstructure usually with good mechanical strength, wear and corrosion resistant properties. Metallographic preparation of these components allows thorough inspection of microstructures, coatings (mainly hydroxyapatite) and potential imperfections from new manufacturing techniques. […]
Selection of the correct mounting compound can make all the difference in achieving high quality preparation. Edge retention compounds such as EpoMet have excellent hardness and shrinkage properties, and are best for hard materials where edge inspection is required as well as for resistance to strong chemical etches. Phenocure is the lowest cost option, and […]
