Vergleichende Untersuchungen zur Partikelgrößenanalyse von Spritzpulvern (Comparative Surveys for Analysing Particle Sizes)

Grain size, grain distibution, morphology and microstructure are essential properties of powders for thermal spaying. The present article concerns with the comparison of different methods of particel size measurement. The results indicate, that the grain distribution differs from method to method and there is no correlation factor existing to convert the results of different test methods. So, for exact stipulation of powder grain sizes the method for determination has to be declared. Paper text in German.
