In this study, SCM440 alloys are investigated to research the effect of wear resistance. For this purpose, three wear factors which are friction force, wear loss and coefficient of friction applied to test wear-resistance. For the wear test, ball-on-disk was used to assess the variation of wear characteristics. Lastly, the coefficient of wear was calculated by using the Archard's wear equation in SCM440 alloys. The applied normal load was fixed at 30N in all test. The test results showed that SCM440 alloy's Vickers hardness average value is near 671.4Hv, the friction force is 4.11N through the Ball-on-disk test, the coefficient of friction and the wear loss are 0.431 and 0.080 respectively. Finally, Archard’s wear value of SCM440 alloys could be shown approximately 0.1514.
