Abstract

Wear is associated with processes leading to the gradual destruction of components, including the impact of physicochemical factors. Determining the relationship between microstructure and working properties of tool steels, including corrosion resistance, has significant importance to the preventing accelerated destruction of tools made of them. The purpose of the tests presented in this paper was to determine the resistance of selected tool steels to corrosion wear. To this end, electrochemical tests and a salt chamber test were carried out. Scanning electron microscope observations carried out after corrosion tests and combined with the earlier microstructural characteristics of the tested materials allowed the accessment of the impact of their microstructure and a clarification of the role of carbides in the development of corrosion.
