Don’t smear it! Avoiding surface deformation in polishing

Different materials have different characteristics, and understanding these can help in ensuring effective specimen preparation is achieved. Aluminum, copper, titanium, nickel and their alloys represent some of the most common engineering materials after steel. These metals can be quite ductile. Materials that deform easily can suffer from plastic deformation during grinding and polishing.  One form …

Metallographic Preparation of Medical Implants – Stents, Orthopedics…

Hip implant image

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. …

“Hot Cell” Metallographic Sample Preparation?!

Hot Cell Chamber with IsoMet

“Hot cells” are shielded nuclear radiation containment chambers or vessels used to handle materials or substances with radioactivity. These chambers have limited space to fit metallographic machines together with mechanical manipulators to handle samples during metallographic preparations. Furthermore, waste generation has to be kept to extremely low levels putting a demand on the type of …
