The Tribological Comportment of the Elaborated Sintered Carbon Steels Based on Fe and Fe_3C Synthetic Nanopowders

摘要

In paper are presented the experimental researches results about the tribological comportment of the elaborated sintered carbon steels based on Fe and Fe_3c synthetic nanopowders.Following the research was obtained sintered carbon steels with more homogeneous structures regarding the uniformity of carbon distribution and implicitly of constituents structural characteristics of use (mechanical) higher compared with carbon steels sintered by classical methods.The best values of the coefficient of friction have carbon steels produced from mixtures of Fe and Fe_3C synthetic nanopowders obtained by mechanical alloy for 30 hours;Depending on the iemperature of sintering respectively pressure tightness, the coefficient of friction decreases with increasing pressure of tightness and temperature sintering.
