Effect of Oxidation Time on Wear Behaviour of Thermally Oxidized CoCrMo Alloy
2020
Onur COMAKLI
CoCrMo alloy has been oxidized for 3 and 5h at the temperature of 850 C with 100% O2 gas by thermal oxidation. The XRD, SEM, microhardness and ball-on-disc wear test devices were used to find out the structure, mechanical and wear properties of untreated and treated specimens. Outcomes showed wear resistance of oxidized specimens were became better than untreated CoCrMo alloy. Also, wear resistance of oxidized specimens improved with increased processing time (from 3h to 5h) increased.
