Summary Polycrystalline iron, low carbon steel, and copper were oxidized thermally at T = 800–870 K in air, and electrochemically in alkaline electrolytes. The growth of the oxide layer and the nature of the oxidation products were analyzed in situ by reflection spectroscopy using a combined setup of a diode array spectrometer for fast recording of the whole spectra and several reflectometers for continuous registration at selected wavelengths and angles of observation. The data were subdivided into specular, off-specular, and diffuse reflectance. On iron and steel, the thermally formed layers grow perfectly linearly with time up to d ≈ 300 nm, and the electrochemically formed layers grow with t 1/2. The latter ones could be separated into a topochemically grown passive film and into a strongly light scattering corrosion layer with bad contact to the substrate.
