Abstract
Iron or nickel substrates were coated with thin films of tin (or boron) and bombarded with 100 keV Xe + ions (or N + ions). Surface modifications were studied using scanning electron microscopy, X-ray diffractometry and Auger electron spectroscopy. The high temperature oxidation of the specimens was studied by two series of experiments. Mass gain data and the observed resulting oxide morphology and composition indicated that the treated surfaces inhibit oxidation in air. Oxidation of other samples in the pre-chamber of the spectrometer and Auger analysis of these samples confirmed the improved oxidation resistance.
