Abstract:	The abrasive wear properties of the bainitic nodular cast iron under different austenitizing and isothermal transformation temperature and time were studied in the present paper. Using Optimol schwingung reibung verschleiss wear tester, the point contact is adopted to compare the effect of those various heat-treatment conditions on wear properties. The weight loss, wear-scar diameter and friction coefficient were measured to evaluate the wear properties. Using scanning electron microscopy, the wear mechanisms can be understood by observing the worn surface. From the results of weight loss, wear-scar diameter and friction coefficient, it can be concluded that the wear resistance increased with increasing austenitizing temperature and the most suitable austempering temperature of the material used in the present study is from 270-300-degrees-C for 4 h.
