The influence of salt composition and oxidation temperature on a series of simple and complex Ni-based alloys was determined. The simple alloys include Ni, Ni-Al, Ni-Cr, and Ni-Cr-Al alloys. The complex alloys include the commercial Ni-base alloys IN-738, B-1900, and NI-50Cr, and a number of high purity laboratory alloys with compositions chosen to simulate the effects of Cr, Al, Mo, Ti, and W. Salt-coated specimens were reacted in a continuous-reading microbalance system in pure oxygen. Oxidized specimens were studied using optical and scanning electron metallography, x-ray diffraction, and microprobe techniques.
