On the Elastic Mechanical Properties of Thermally Sprayed Coatings

This paper aims to evaluate various measurement methods for characterizing the elastic behavior of thermally sprayed composites. The behavior of layered composite materials is determined by the interplay of residual stresses, load stresses, and bonding strength. Measuring Young's modulus in such coatings can be difficult, however, due to brittleness and inhomogeneities in microstructure. In this work, the authors determine both the influence of the indentation load on Young's modulus and that of the analysis method. Paper includes a German-language abstract.
