The influence of environment on corrosion of cast iron and carbon steel representing samples of outdoor metal technical heritage

摘要: This paper presents the results of annual measurements corrosion progress at test samples cast iron and carbon steel placed in different natural environments. Comparative tests were performed two outdoor stations, one Railway Museum central Warsaw location a small town Sochaczew, 50 km west Warsaw. The influence surface roughness on development was determined by kinds treatment all sample surfaces − metal brush or grinding. Stratigraphy composition products quarterly periods analyzed with laser-induced breakdown spectroscopy (LIBS) Raman laser spectroscopy. using scanning electron microscopy (SEM) system equipped energy dispersive spectrometer (EDS) micro-chemical analytical methods. layers have proven to be thicker average than iron, brushed parts both materials. Furthermore, layer found exposed Sochaczew Different oxides, namely lepidocrocite, goethite, hematite magnetite identified spectra layers, last compound only from Sochaczew. SEM EDS elemental concentrations showed higher concentration sulfur Registered LIBS been additionally statistical approach, Factorial Analysis (FA). Results generally confirmed conclusions drawn SEM/Raman/LIBS results.
