Investigation of ASTM F75 Co-Cr-Mo alloy's abrasive wear behavior

In this study, abrasive wear behaviors of Co-Cr-Mo alloy (ASTM F75) which is produced by casting method, were investigated. The prepared test samples were subjected to abrasive wear tests with different emery papers on the pin on disc wear device. In the abrasive tests, 400, 600 and 800 mesh emery papers were used and abrasive wear tests were performed under loads of 5, 10 and 20N. The tests were carried out at 22 oC temperature, at a shear rate of 0.8 m / s and at a length of 100 cm shear distance. EDS elemental analysis was performed to investigate the elements and chemical constituents on the surfaces of the samples and EFM surface analysis was performed to examine the qualities and roughness of the surfaces. The obtained results showed less weight loss at the higher meshes. It was observed that better quality surfaces were found in tests which were performed in higher mesh sizes
