DiaMet Hardness Software – Weld Testing Using Vickers Hardness Scale

Weld Image

Welded joints are nowadays indispensable in the automotive and aviation industry. Welds usually combine metallic components to form a structure that is then assembled in production and assembly with other subassemblies. The welds must be able to withstand extreme loads as they are the weak points of the construction. Weld seam inspection is thus a …

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 …
