Effect of Preparation on the Correct Interpretation of Thermal Spray Coatings on the Basis of Selected Atmospheric Plasma and Flame Spray Coatings

Abstract For quality assurance, thermal spray coatings undergo, metallographic examination, among other things, Here, for example, unmelted particles, pores, oxides, phase fractions, homogeneity, separations, cracks and impurities are estimated. The correct evaluation of thermal spray samples is heavily influenced by embedding and preparation methods.
