摘要：

We studied the influence of oxygen-containing (6.10(-3) wt.% O) lead on the corrosion of Armco iron and Fe-16Cr, Fe-16Cr-1Al alloys at a temperature of 650 degrees C under stationary conditions. The front of corrosion propagates according to a linear law and this process is periodically repeated. In each period, an oxide film based on Fe3O4 magnetite is formed on the surface of the metal and lead penetrates into the suboxide zone. This leads to the exfoliation the external oxide film and then the process is repeated. Under the indicated testing conditions, alloying with chromium and aluminum intensifies the process of corrosion in iron.
