Resumo
During the wear process, significant changes can be observed in the microstructure of the contact zone and the near surface region below it. This is due to a high intensity of plastic deformation which occurs. For this reason, it is difficult to use the typical parameters of the initial microstructure to describe the wear behaviour. In this study, depending on the work hardening induced during the abrasion process, a new model "Equivalent Hardness" has been developed to describe the abrasive wear behaviour. Using this model, the wear behaviour of different iron-base alloys with and without hard phases could easily be explained, whereas the typical initial parameters such as macro- and microhardness, retained austenite, and carbide volume fraction were not sufficient to discuss the wear performance.
