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. …
