استفاده از سنگ ساینده جهت ارزیابی رفتار سایشی فولادها

In this paper, how to use the abrasive wheel in the pin on disk test was evaluated and developed for tribological studies of steels. Parameters such as type of pin (steel), type of abrasive wheel, normal load on pin, linear velocity of disk and sliding distance were studied. The results showed that initial hardness can not merely determine the wear resistance of a metal whereas it may be related to the surface hardness resulting from work hardening during abrasive. In addition, in the pin on disk method, using the abrasive wheel is a good choice for evaluation of tribological behavior of high wear resistance metals such as Hadfield steels while, it is not appropriate and proper for mild steel.
