Abstract

The presented thesis is devoted to the corrosion resistance assessment of an austenitic stainless steel with high boron content. Exposure tests were executed for steels, differing in the way of manufacturing, in an aqueous solution of boric acid for determination of the corrosion rate. By optical and scanning electron microscope, the structure of particles diffused in the matrix was observed. Both the results of microhardness test and chemical composition data, determined by EDS method, confirmed assumption, that they can be (Cr, Fe)2B borides.
