Effect of Nozzle Design and Atomization Gas on the Properties of Electric Arc Sprayed Ni18Cr6Al2Mn Coatings Available to Purchase

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.
