摘要

Time-of-flight secondary ion mass spectrometry profiling, scanning transmission electron microscopy, and energy dispersive X-ray mapping were used to investigate physical and chemical processes on the surface of a precipitation-hardenable nickel-chromium alloy associated with single or multiple heating/cooling cycles that simulate typical service conditions of aircraft products made of such alloys. Research findings show the growth of oxide, increase of surface roughness, and microstructural changes. The depth distribution of main metal oxides is discussed. It was determined that aluminum diffusing along the alloy grain boundaries forms an oxide on the surface and intergranular Al2O3. The Ti and Nb nitride inclusions were found to appear after the first oxidation cycle. (C) 2015 Elsevier B.V. All rights reserved.
