Accurate Porosity Measurement in Thermal Spray Coatings

Porosity in a Thermal Spray Coating

Coatings manufactured via thermal spray typically have porosity in them. One of the most common processes for characterizing a spray coating is metallographic preparation. However, it’s long been established that there can be problems in both finding a correct approach to preparation, and to reproducing this approach over time.  A good method is only part …

Sample mounting – when method selection really matters!

EpoKwick FC

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 …

Sectioning of Electronic Components

IsoMet High Speed

Introduction Sectioning of electronic components for quality control or failure analysis can be challenging as care must be taken to ensure the true structure is revealed, free from preparation-induced artifacts. Historically, sectioning processes that were highly damaging to the sample were used, which could induce artifacts that could easily be misinterpreted as manufacturing defects or …

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. …
