Toosi University of Technology, Tehran, Iran Journal Article 2024 12 31 CoCrMo alloys having good corrosion resistance  and high mechanical properties as well as good biocompatibility, are widely used in biological applications such as implants. As wear resistance of these parts is important, in this work, the effects of applied load and wear distance on the tribological behavior of CoCrMo alloy produced by powder bed fusion of metals using a laser beam method have been evaluated. Results showed that by increasing the applied force, the amount of volume lost increases according to a two-degree polynomial equation.  Also, it was observed that by increasing the sliding distance from 500 to 1000 m, the total volume loss increases  from 1500 to 2500 mm³ and the wear mechanism changes from severe abrasion to adhesion and weak abrasion.
