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 …
