Characterization of the Thermal Spray Coatings Having Amorphous and Nanocrystalline Structure

In this paper, the morphology, the microstructure, the thermal stability ranges, the devitrification kinetics, and the hardness of amorphous detonation sprayed FeCrPC coatings are examined and compared with those of amorphous tapes of similar composition. Nanocoatings were made by heat treating the amorphous coatings. It is observed that thermal spraying (using the detonation gun method) produced coatings with an improved thermal stability of the amorphous component. Paper includes a German-language abstract.
