Abstract

The aim of this study was to analyse and to identify the phases which formed in 100CrMnSi6-4 bearing steel after the nanostructuring heat treatment. Especially designed thermal treatment parameters were applied in order to obtain a nanobainitic structure. Two different microscopic techniques were used for the precise examination of the microstructures obtained: transmission electron microscopy (TEM) and atomic force microscopy (AFM). Both analyses confirm that the examined steel has a nanocrystalline structure. However, it was discovered that the selected analysis methods affected the results of the plate thickness measurements.

Proton exchange membrane fuel cells (PEMFCs) are numbered among low-temperature cells. Their operating temperature reaches 120°C, whereas their efficiency amounts to ca. 40%. These cells are most often used for the batteries for portable devices, low and high power generators, stationary power plants and car drives. The PEMFCs are composed of the membrane, electrodes at both sides and bipolar plates, also termed interconnectors. The main aim of the present study was to investigate the sintered stainless steels in simulated environments of a PEM fuel cells for bipolar plates. The ferritic (434L) and austenitic (316L) stainless steels were examined. The corrosion properties were examined in 0.1 mol dm-3 Na2SO4 + 2 ppmF-(pH= 1; 3; 5) at 80°C.
