摘要:The steel presents a wide feld of application. The abrasive wear resistance of steel relies mainly on the microstructure, hardness as well as on the abrasive material properties. Moreover, the selection of a abrasion-resistantgrade of steel still seems to be a crucial and unsolved problem, especially due to the fact that the actual operatingconditions can be affected by the presence of different abrasive materials. The aim of this work was to determinethe effect of different abrasive grit materials i.e. garnet, corundum and carborundum on the abrasive wear result ofa commonly used in industry practice steels i.e. S235, S355, C45, AISI 304 and Hardox 500. The microstructure ofthe steel was investigated using light optical microscopy. Moreover, hardness was measured with Vickers hardnesstester. Additionally, the size and morphology of the abrasive materials were characterized. The abrasion tests wereconducted with the usage of T-07 tribotester (dry sand rubber wheel). The results demonstrate that the hardnessand structure of steels and hardness of abrasive grids influenced the wear results. The abrasive wear behavior ofsteels was dominated by microscratching and microcutting wear mechanisms. The highest mass loss was obtainedfor garnet, corundum, and carborundum, respectively. The usage of various abrasives results in different abrasionresistance for each tested steel grade. The AISI 304 austenitic stainless steel presents an outstanding abrasive wearresistance while usage of corundum and Hardox 500 while using a garnet as abrasive material. The C45 carbonsteel was less resistant than AISI 304 for all three examined abrasives. The lowest resistance to wear in garnet andcarborundum was obtained for the S235JR and S355J2 ferritic-perlitic carbon steels and in corundum for Hardox500 which has tempered martensitic structure.
