Abstract

A composite made from a mixture of iron and copper powders was produced and characterised. The Cu addition favours the production of sintered Fe in the powder metallurgy industry processes. The corrosion behaviour in different electrolytic solution (sodium chloride or hydrochloric, acetic or sulphuric acids) and the corrosion rates were obtained from the weight loss and potentiodynamic methods – intersection and linear polarisation resistance. The values in hydrochloric and sulphuric acid vary slightly with respect to the average value of 78 mV/decade. The values obtained in acetic acid and sodium chloride are higher probably due to the formation of a thin film layer over the metallic surface. The morphology was analyzed through the observation by optical and scanning electron microscopy. It has been determined the nature of the oxide layer, Fe~3~O~4~, by X‐ray photoelectron spectroscopy (XPS), isolating the composite from the atmosphere. Thus, this oxide layer acts as a corrosion protective surface.

High purity Fe±50 mass% Cr alloys containing C and N in a range of 30 to 500 mass ppm were prepared and their corrosion resistance was investigated. A field exposure test at a coastal area showed that the decrease of the C and N content decreases the number and depth of corrosion pits. The alloys co
