Tribocorrosion modeling of stainless steel in a sliding pair of pin-on-plate type

In this paper, the results of research into tribocorrosion wear of three types of stainless steel: AISI 430, 304 and 420 are presented. The research was carried out on a pin-on-plate stand in a 0.5 M solution of H2SO4. The aim of the research was to define relations between original properties of steel (resistance to abrasion and corrosion) and the intensity of tribocorrosion wear.Moreover, the authors present their own computational model allowing to forecast the effects of tribocorrosion in pin-on-plate type combination. As concerns forecasting the intensity of tribocorrosion, the authors state that maximum differences did not exceed 15%.

► The authors present model allowing prediction of tribocorrosion in sliding pair. ► In this model elementary interaction is analyzed within of real contact area. ► The results of tribotests were used for the evaluation of the efficacy of this model. ► Maximum differences (the results of the computations and tests) did not exceed 15%.
