The application of wear maps for analyzing the results of research into tribocorrosion

Tribocorrosion maps were prepared for two types of corrosion resistant stainless steels that have different properties; namely, AISI 304 and AISI 420. The maps were based on data from a pin-on-plate geometry tested in a 0.5 M solution of H2SO4 at passive potential polarization. A coordinate system was designed to normalize the effects of applied variables and material properties. In order to obtain an adequate amount of data for these maps, the results of experiments were combined with the results of simulative computations. The resulting tribocorrosion maps rendered it possible to identify certain differences and similarities with respect to the effects of material properties and the conditions of use on the intensity of wear for the two stainless steels. Synthetized maps indicated a correlation of the wear intensities of steels within one particular wear mode. (C) 2016 Elsevier B.V. All rights reserved.
