In this study, powder metal (P/M) compacts were prepared by mixing iron powder with 0-1 wt.-% Al, 2-3 wt.-% Cu and 0.2-0.8 wt.-% graphite. The 16 different P/M compacts compositions were prepared with 0.8 wt.-% zinc stearate as lubricant. The compacts' dimensions were 10 × 10 × 55 mm. All compacts were pressed at 600 MPa and sintered at 1120 °C for 30 minutes using a conventional sintering furnace and then boronizing, steaming and carbonitriding heat treatments were applied. The results of all the compacts in regard of the effects of corrosion endurance, density, and HV microhardness results were compared. © Carl Hanser Verlag GmbH & Co. KG.
