将AISI 304和316型不锈钢在空气中加热（在900-1000- 1100 °C下加热1-5-15分钟），并通过XRD、CEMS、SIMS和FTIR分析表面上形成的氧化物层。在这些温度下，抛光样品的主要氧化物是Cr2 O3和接近MnCr 2 O 4的尖晶石（化学清洁样品为Fe 2 O3）。氧化引起金属基体中Cr和Mn的贫化和γ（f.c.c.）在靠近氧化物-金属界面的薄层中，α →（b.c.c）。
Stainless steels of type AISI 304 and 316 were heated in air (1-5-15 minutes at 900-1000-1100 °C) and the oxide layers formed on the surface were analyzed by XRD, CEMS, SIMS and FTIR. At these temperatures the main oxides are Cr2O3 and a spinel close to MnCr2O4 for polishing samples (with Fe2O3 for the chemically cleaned samples). The oxidation induces a Cr and Mn depletion from the metallic substratum and a phase transformation γ (f.c.c.) → α (b.c.c) in a thin layer of the steels near the oxides - metal interface.
