Wear Behavior of Fe-Cr-C Sintered Steels

Abstract:

The paper is focused on the elaboration of some sintered steels with Cr concentration between (1-2 %) wt., carbon as graphite with a concentration of 0,4% wt. and Fe for the balance. The samples were die pressed at 600 MPa and sintered at 1150 °C in argon atmosphere. The samples were studied from the point of view of wear behavior against three types of counter balls, alumina (Al₂O₃), steel (100Cr6) and stainless steel 440C. The results shows that the lowest value for the friction coefficient was attained for the steel with 1,5% Cr. Also, microhardness tests were performed and reveal that the highest value was equal to 229 HV_05.
