Abstract
The study was an investigation whether sintered Fe-2.5%Mn-0.8%C steel is suitable for production of gears. Base powders, iron grade Höganäs NC 100. 24, low carbon ferromanganese (77%Mn, 23%Fe and 1.3%C) and graphite C-UF, were mixed in a Turbula TC2 mixer. Subsequently the mixture was sent to the Bulgarian company SinterM, Jambol, where a pilot set of gears was made in industrial conditions. Some green compacts were laboratory sintered at AGH, Krakow, at 1120°C and 1250°C for 60 minutes in the mixture of 95%N2-5%H2 (different from an industrial atmosphere) and sinterhardened (rapidly cooled from the sintering temperature with cooling rate~1K/s). A set was sintered in Jambol at 1150°C for 60 minutes in an industrial furnace in an atmosphere of 70%N2-30%H2. These are the gear sintering conditions for their currently used steel, Fe-1.75% Ni-1.50% Cu-0.50% Mo0.6%С, from base powders Distaloy AB, iron powder ASC 100.29 and graphite. Measurements were made of density and tooth resistance to bending, and metallographic and fractographic observations made of gears, both sintered in Bulgaria and in Krakow. The highest tooth resistance to bending was for Mn steel gears, ~1260 MPa, laboratory sintered at 1250°C or industrially sintered at 1150°C, which was about 100MPa less when sintered at 1120°C, still ~100MPa above the performance of Fe-1.75% Ni-1.50% Cu-0.50% Mo-0.6%С.
