5.11.7 Thermal Spray Coatings
The metallographic specimen preparation of thermal spray coatings is
affected by the specimen composition and deposition conditions.
Microstructural features of interest include: porosity, flow, thickness and
inclusions. Proper metallurgical preparation takes into account that the
microstructure may be porous and perhaps somewhat brittle because of
inadequate processing.
