This paper evaluates various methods for adjusting the degree of oxidation in arc-sprayed layers. Oxidation control is primarily achieved through the use of a nonoxidizing gas, such as argon or nitrogen, especially in combination with a fine nozzle. In the case of Ni18Cr6Al2Mn deposits, the measured oxide content varied from 0.85 to 3.41 wt% based on the atomizing gas, nozzle, and stand-off distance used. Paper includes a German-language abstract.
