Abstract The use of the wire arc spray process for the production of zinc and aluminum coatings as corrosion protection represents a rapidly growing market. In this paper, the effects of various spray parameters on the performance of the process for these materials are examined. The effects of arc voltage, current, and wire diameter have been studied for their effects on the main factors affecting process performance, spray performance, and application efficiency. The results of this study have led to the development of a spray system or a power supply to maximize the performance of the process for corrosion protection applications.

Abstract 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.
