  • Cutting Edge Hardness Testing

    Quality assessment of cutting blades has its challenges, but these can be overcome. Technique and attention to details with specimen preparation is a key factor to success. Having the specimen flat with no edge rounding will allow an indent to be placed near the blade tip. The use of semi...
  • Case Hardened Steels - Induction Hardened

    Induction hardening of steel components involves raising the temperature of the surface layer to where it’s transformed to austenite and rapidly cooling to produce a hard martensitic microstructure. This is mainly done on hardenable steels although some carburized steels are often reheated...
  • Metallographic Preparation of Medical Implants – Stents, Orthopaedics…

    The article has highlighted different alloys and coatings used in medical implants. Medical implants are increasingly being used due to good mechanical strength, wear and corrosion resistant properties, super elasticity and most importantly biocompatibility. For metallographic analysis of these...
  • TIME STUDY: CASE HARDNESS TESTING OF AUTOMOTIVE CRANK PINS AND JOURNALS:

    A study shows an operator time savings of 86% for making and measuring indents in three locations of crank pins and journals when using Buehler's hardness automation compared to manual testing. There was less part manipulation, fewer errors in data transcription and lower variability between...
