The Effect of NaCl ( g ) on the Oxidation of NiAl

Abstract
Is ingested into operating gas turbines. The effect of this salt on the high temperature surface stability properties of turbine hardware is not well understood. The involvement of in the high temperature oxidation of , a principal component in many high temperature environmental coatings, is herein examined. The results of this work indicate that present in an oxidizing atmosphere affects the formation of whiskers on a dense layer. Such whisker growth, attributed to vapor transport processes through an otherwise dense scale. increases the aluminum depletion of the substrate.
